ICA supports running pipelines defined using Common Workflow Language (CWL).
To specify a compute type for a CWL CommandLineTool, use the ResourceRequirement with a custom namespace.
Reference Compute Types for available compute types and sizes.
The ICA Compute Type will be determined automatically based on CWL ResourceRequirement coresMin/coresMax (CPU) and ramMin/ramMax (Memory) values using a "best fit" strategy to meet the minimum specified requirements (refer to the Compute Types table).
For example, take the following ResourceRequirements:
This would result in a best fit of standard-large ICA Compute Type request for the tool.
If the specified requirements can not be met by any of the presets, the task will be rejected and failed.
FPGA requirements can not be set by means of CWL ResourceRequirements.
The Machine Profile Resource in the graphical editor will override whatever is set for requirements in the ResourceRequirement.
If no Docker image is specified, Ubuntu will be used as default. Both : and / can be used as separator.
ICA supports overriding workflow requirements at load time using Command Line Interface (CLI) with JSON input. Please refer to CWL documentation for more details on the CWL overrides feature.
In ICA you can provide the "override" recipes as a part of the input JSON. The following example uses CWL overrides to change the environment variable requirement at load time.
Let's create the Nextflow Scatter Gather pipeline with a JSON input form.
Pay close attention to uppercase and lowercase characters when creating pipelines.
Select Projects > your_project > Flow > Pipelines. From the Pipelines view, click the +Create pipeline > Nextflow > JSON based button to start creating a Nextflow pipeline.
In the Details tab, add values for the required Code (unique pipeline name) and Description fields. Nextflow Version and Storage size defaults to preassigned values.
First, we present the individual processes. Select Nextflow files > + Create file and label the file split.nf. Copy and paste the following definition.
Next, select +Create file and name the file sort.nf. Copy and paste the following definition.
Select +Create file again and label the file merge.nf. Copy and paste the following definition.
Edit the main.nf file by navigating to the Nextflow files > main.nf tab and copying and pasting the following definition.
Here, the operators flatten and collect are used to transform the emitting channels. The Flatten operator transforms a channel in such a way that every item of type Collection or Array is flattened so that each single entry is emitted separately by the resulting channel. The collect operator collects all the items emitted by a channel to a List and return the resulting object as a sole emission.
On the Inputform files tab, edit the inputForm.json to allow selection of a file.
Click the Simulate button (at the bottom of the text editor) to preview the launch form fields.
The onSubmit.js and onRender.js can remain with their default scripts and are just shown here for reference.
Click the Save button to save the changes.
A Pipeline is a series of Tools with connected inputs and outputs configured to execute in a specific order.
Pipelines are created and stored within projects.
Navigate to Projects > your_project > Flow > Pipelines.
Select CWL or Nextflow to create a new Pipeline.
Configure pipeline settings in the pipeline property tabs.
When creating a graphical CWL pipeline, drag connectors to link tools to input and output files in the canvas. Required tool inputs are indicated by a yellow connector.
Select Save.
Pipelines use the latest tool definition when the pipeline was last saved. Tool changes do not automatically propagate to the pipeline. In order to update the pipeline with the latest tool changes, edit the pipeline definition by removing the tool and re-adding it back to the pipeline.
Individual Pipeline files are limited to 100 Megabytes. If you need to add more than this, split your content over multiple files.
Pipelines use the latest tool definition when the pipeline was last saved. Tool changes do not automatically propagate to the pipeline. In order to update the pipeline with the latest tool changes, edit the pipeline definition by removing the tool and re-adding it back to the pipeline.
You can edit pipelines while they are in Draft or Release Candidate status. Once released, pipelines can no longer be edited.
The following sections describe the tool properties that can be configured in each tab of the pipeline editor.
Depending on how you design the pipeline, the displayed tabs differ between the graphical and code definitions. For CWL you have a choice on how to define the pipeline, Nextflow is always defined in code mode.
Any additional source files related to your pipeline will be displayed here in alphabetical order.
See the following pages for language-specific details for defining pipelines:
The Information tab provides options for configuring basic information about the pipeline.
The following information becomes visible when viewing the pipeline.
In addition, the clone function will be shown (top-right). When cloning a pipeline, you become the owner of the cloned pipeline.
The Documentation tab provides options for configuring the HTML description for the tool. The description appears in the tool repository but is excluded from exported CWL definitions. If no documentation has been provided, this tab will be empty.
When using graphical mode for the pipeline definition, the Definition tab provides options for configuring the pipeline using a visualization panel and a list of component menus.
In graphical mode, you can drag and drop inputs into the visualization panel to connect them to the tools. Make sure to connect the input icons to the tool before editing the input details in the component menu. Required tool inputs are indicated by a yellow connector.
This page is used to specify all relevant information about the pipeline parameters.
The Analysis Report tab provides options for configuring pipeline execution reports. The report is composed of widgets added to the tab.
The pipeline analysis report appears in the pipeline execution results. The report is configured from widgets added to the Analysis Report tab in the pipeline editor.
[Optional] Import widgets from another pipeline.
Select Import from other pipeline.
Select the pipeline that contains the report you want to copy.
Select an import option: Replace current report or Append to current report.
Select Import.
From the Analysis Report tab, select Add widget, and then select a widget type.

Multiple files can be added to make pipelines more modular and manageable.
Syntax highlighting is determined by the file type, but you can select alternative syntax highlighting with the drop-down selection list. The following formats are supported:
DIFF (.diff)
GROOVY (.groovy .nf)
JAVASCRIPT (.js .javascript)
JSON (.json)
SH (.sh)
SQL (.sql)
TXT (.txt)
XML (.xml)
YAML (.yaml .cwl)
For each process defined by the workflow, ICA will launch a compute node to execute the process.
For each compute type, the standard (default - AWS on-demand) or economy (AWS spot instance) tiers can be selected.
When selecting an fpga instance type for running analyses on ICA, it is recommended to use the medium size. While the large size offers slight performance benefits, these do not proportionately justify the associated cost increase for most use cases.
When no type is specified, the default type of compute node is standard-small.
By default, compute nodes have no scratch space. This is an advanced setting and should only be used when absolutely necessary as it will incur additional costs and may offer only limited performance benefits because it is not local to the compute node.
For simplicity and better integration, consider using shared storage available at /ces. It is what is provided in the Small/Medium/Large+ compute types. This shared storage is used when writing files with relative paths.
Daemon sets and system processes consume approximately 1CPU and 2GB Mem from the base values shown in the table. Consumption will vary based on the activity of the pod.
* The compute type "fpga-small" is no longer available. Use 'fpga-medium' instead. fpga-large offers little performance benefit at additional cost.
** The transfer size selected is based on the selected storage size for compute type and used during upload and download system tasks.

Pipelines defined using the "Code" mode require either an XML-based or JSON-based input form to define the fields shown on the launch view in the user interface (UI). The XML-based input form is defined in the "XML Configuration" tab of the pipeline editing view.
The input form XML must adhere to the input form schema.
During the creation of a Nextflow pipeline the user is given an empty form to fill out.
The input files are specified within a single DataInputs node. An individual input is then specified in a separate DataInput node. A DataInput node contains following attributes:
code: an unique id. Required.
format: specifying the format of the input: FASTA, TXT, JSON, UNKNOWN, etc. Multiple entries are possible: example below. Required.
type: is it a FILE or a DIRECTORY? Multiple entries are not allowed. Required.
required: is this input required for the execution of a pipeline? Required.
multiValue: are multiple files as an input allowed? Required.
dataFilter: TBD. Optional.
Additionally, DataInput has two elements: label for labelling the input and description for a free text description of the input.
An example of a single file input which can be in a TXT, CSV, or FASTA format.
To use a folder as an input the following form is required:
For multiple files, set the attribute multiValue to true. This will make it so the variable is considered to be of type list [], so adapt your pipeline when changing from single value to multiValue.
Settings (as opposed to files) are specified within the steps node. Settings represent any non-file input to the workflow, including but not limited to, strings, booleans, integers, etc. The following hierarchy of nodes must be followed: steps > step > tool > parameter. The parameter node must contain following attributes:
code: unique id. This is the parameter name that is passed to the workflow
minValues: how many values (at least) should be specified for this setting. If this setting is required, minValues should be set to 1.
maxValues: how many values (at most) should be specified for this setting
classification: is this setting specified by the user?
In the code below a string setting with the identifier inp1 is specified.
Examples of the following types of settings are shown in the subsequent sections. Within each type, the value tag can be used to denote a default value in the UI, or can be left blank to have no default. Note that setting a default value has no impact on analyses launched via the API.
For an integer setting the following schema with an element integerType is to be used. To define an allowed range use the attributes minimumValue and maximumValue.
Options types can be used to designate options from a drop-down list in the UI. The selected option will be passed to the workflow as a string. This currently has no impact when launching from the API, however.
Option types can also be used to specify a boolean, for example
For a string setting the following schema with an element stringType is to be used.
For a boolean setting, booleanType can be used.
One known limitation of the schema presented above is the inability to specify a parameter that can be multiple type, e.g. File or String. One way to implement this requirement would be to define two optional parameters: one for File input and the second for String input. At the moment ICA UI doesn't validate whether at least one of these parameters is populated - this check can be done within the pipeline itself.
Below one can find both a main.nf and XML configuration of a generic pipeline with two optional inputs. One can use it as a template to address similar issues. If the file parameter is set, it will be used. If the str parameter is set but file is not, the str parameter will be used. If neither of both is used, the pipeline aborts with an informative error message.
Pipelines defined using the "Code" mode require an XML or JSON-based input form to define the fields shown on the launch view in the user interface (UI).
To create a JSON-based Nexflow (or CWL) pipeline, go to Projects > your_project > flow>pipelines>create pipeline>Nextflow (or CWL) > JSON-based.
Three files, located on the inputform files tab, work together for evaluating and presenting JSON-based input.
inoutForm.json contains the actual input form which is rendered when staring the pipeline run.
onRender.js is triggered when a value is changed.
onSubmit.js is triggered when submitting a new pipeline execution request via the GUI or API.
Use + Create file to add additional files and Simulate to test your inputForms.
Scripting execution supports crossfield validation of the values, hiding fields, making them required, .... based on value changes.
The json schema allowing you to define the input parameters. See the inputForm.json page for syntax details.
| Type | Usage |
|---|---|
These attributes can be used to configure all parameter types.
The onSubmit.js javascript function receives an input object which holds information about the chosen values of the input form and the pipeline and pipeline execution request parameters. This javascript function is not only triggered when submitting a new pipeline execution request in the user interface, but also when submitting one through the rest API..
Receives an input object which contains information about the current state of the input form, the chosen values and the field value change that triggered the onrender call. It also contains pipeline information. Changed objects are present in the onRender return value object. Any object not present is considered to be unmodified. Changing the storage size in the start analysis screen triggers an onRender execution with storageSize as changed field.
This is the object used for representing validation errors and warnings. The attributes can be used with first letter lowercase (consistent with the input object attributes) or uppercase.
ICA supports running pipelines defined using Nextflow. See this tutorial for an example.
In order to run Nextflow pipelines, the following process-level attributes within the Nextflow definition must be considered.
| Info | Details |
|---|---|
You can select the Nextflow version while building a pipeline as follows:
| interface | |
|---|---|
For each compute type, you can choose between the scheduler.illumina.com/lifecycle: standard (default - AWS on-demand) or scheduler.illumina.com/lifecycle: economy (AWS spot instance) tiers.
To specify a compute type for a Nextflow process, use the pod directive within each process. Set the annotation to scheduler.illumina.com/presetSize and the value to the desired compute type. A list of available compute types can be found here. The default compute type, when this directive is not specified, is standard-small (2 CPUs and 8 GB of memory).
Often, there is a need to select the compute size for a process dynamically based on user input and other factors. The Kubernetes executor used on ICA does not use the cpu and memorydirectives, so instead, you can dynamically set the pod directive, as mentioned here. e.g.
Additionally, it can also be specified in the configuration file. Example configuration file:
Inputs are specified via the XML input form or JSON-based input form. The specified code in the XML will correspond to the field in the params object that is available in the workflow. Refer to the tutorial for an example.
Outputs for Nextflow pipelines are uploaded from the out directory in the attached shared filesystem. The publishDir directive can be used to symlink (recommended), copy or move data to the correct folder. Data will be uploaded to the ICA project after the pipeline execution completes.
For Nextflow version 20.10.10 on ICA, using the "copy" method in the publishDir directive for uploading output files that consume large amounts of storage may cause workflow runs to complete with missing files. The underlying issue is that file uploads may silently fail (without any error messages) during the publishDir process due to insufficient disk space, resulting in incomplete output delivery.
Workarounds:
Use "symlink" instead of "copy" in the publishDir directive. Symlinking creates a link to the original file rather than copying it, which doesn’t consume additional disk space. This can prevent the issue of silent file upload failures due to disk space limitations.
Use the latest version of Nextflow supported (22.04.0) and enable the "failOnError" publishDir option. This option ensures that the workflow will fail and provide an error message if there's an issue with publishing files, rather than completing silently without all expected outputs.
During execution, the Nextflow pipeline runner determines the environment settings based on values passed via the command-line or via a configuration file (see Nextflow Configuration documentation). When creating a Nextflow pipeline, use the nextflow.config tab in the UI (or API) to specify a nextflow configuration file to be used when launching the pipeline.
Syntax highlighting is determined by the file type, but you can select alternative syntax highlighting with the drop-down selection list.
If no Docker image is specified, Ubuntu will be used as default.
The following configuration settings will be ignored if provided as they are overridden by the system:
Developing on the cloud incurs inherent runtime costs due to compute and storage used to execute workflows. Here are a few tips that can facilitate development.
Leverage the cross-platform nature of these workflow languages. Both CWL and Nextflow can be run locally in addition to on ICA. When possible, testing should be performed locally before attempting to run in the cloud. For Nextflow, configuration files can be utilized to specify settings to be used either locally or on ICA. An example of advanced usage of a config would be applying the scratch directive to a set of process names (or labels) so that they use the higher performance local scratch storage attached to an instance instead of the shared network disk,
When trying to test on the cloud, it's oftentimes beneficial to create scripts to automate the deployment and launching / monitoring process. This can be performed either using the ICA CLI or by creating your own scripts integrating with the REST API.
For scenarios in which instances are terminated prematurely (for example, while using spot instances) without warning, you can implement scripts like the following to retry the job a certain number of times. Adding the following script to 'nextflow.config' enables five retries for each job, with increasing delays between each try.
Note: Adding the retry script where it is not needed might introduce additional delays.
When hardening a Nextflow to handle resource shortages (for example exit code 2147483647), an immediate retry will in most circumstances fail because the resources have not yet been made available. It is best practice to use Dynamic retry with backoff which has an increasing backoff delay, allowing the system time to provide the necessary resources.
When publishing your Nextflow pipeline, make sure your have defined a container such as 'public.ecr.aws/lts/ubuntu:22.04' and are not using the default container 'ubuntu:latest'.
To limit potential costs, there is a timeout of 96 hours: if the analysis does not complete within four days, it will go to a 'Failed' state. This time begins to count as soon as the input data is being downloaded. This takes place during the ICA 'Requested' step of the analysis, before going to 'In Progress'. In case parallel tasks are executed, running time is counted once. As an example, let's assume the initial period before being picked up for execution is 10 minutes and consists of the request, queueing and initializing. Then, the data download takes 20 minutes. Next, a task runs on a single node for 25 minutes, followed by 10 minutes of queue time. Finally, three tasks execute simultaneously, each of them taking 25, 28, and 30 minutes, respectively. Upon completion, this is followed by uploading the outputs for one minute. The overall analysis time is then 20 + 25 + 10 + 30 (as the longest task out of three) + 1 = 86 minutes:
If there are no available resources or your project priority is low, the time before download commences will be substantially longer.
By default, Nextflow will not generate the trace report. If you want to enable generating the report, add the section below to your userNextflow.config file.

select
A dropdown selection to select one from a list of choices.
radio
A radio button group to select one from a list of choices.
data
Data such as files.
fieldgroup
Can contain parameters or other groups. Allows to have repeating sets of parameters, for instance when a father|mother|child choice needs to be linked to each file input. So if you want to have the same elements multiple times in your form, combine them into a fieldgroup.
label
The display label for this parameter. Optional but recommended, id will be used if missing.
minValues
The minimal amount of values that needs to be present. Default when not set is 0. Set to >=1 to make the field required.
maxValues
The maximal amount of values that need to be present. Default when not set is 1.
minMaxValuesMessage
The error message displayed when minValues or maxValues is not adhered to. When not set, a default message is generated.
helpText
A helper text about the parameter. Will be displayed in smaller font with the parameter.
placeHolderText
An optional short hint ( a word or short phrase) to aid the user when the field has no value.
value

minLength
Only applied on type="textbox". Value is a positive integer.
maxLength
Only applied on type="textbox". Value is a positive integer.
min
Applied on type="number" and type="integer". Value must correspond to the primitive type.
max
Applied on type="number" and type="integer". Value must correspond to the primitive type.
choices
A list of choices with for each a "value", "text" (is label), "selected" (only 1 true supported), "disabled". "parent" can be used to build hierarchical choicetrees. "availableWhen" can be used for conditional presence of the choice based on values of other fields.
fields
The list of sub fields for type fieldgroup.
dataFilter
For defining the filtering when type is 'data'. nameFilter, dataFormat and dataType are additional properties.
regex
The regex pattern the value must adhere to. Only applied on type="textbox".
regexErrorMessage
The optional error message when the value does not adhere to the "regex". A default message will be used if this parameter is not present. It is highly recommended to set this as the default message will show the regex which is typically very technical.
hidden
Makes this parameter hidden. Can be made visible later in onRender.js or can be used to set hardcoded values of which the user should be aware.
disabled
Shows the parameter but makes editing it impossible. The value can still be altered by onRender.js.
emptyValuesAllowed
When maxValues is 1 or not set and emptyValuesAllowed is true, the values may contain null entries. Default is false.
updateRenderOnChange
When true, the onRender javascript function is triggered each time the user changes the value of this field. Default is false.
settings
The value of the setting fields. Corresponds to settingValues in the onRender.js. This is a map with field id as key and an array of field values as value. For convenience, values of single-value fields are present as the individual value and not as an array of length 1. In case of fieldGroups, the value can be multiple levels of arrays.
settingValues
To maximize the opportunity for reusing code between onRender and onSubmit, the 'settings' are also exposed as settingValues like in the onRender input.

storageSizeOptions
The list of storage sizes available to the user when creating an analysis. Is a list of StorageSize objects containing an 'id' and 'name' property.
settings
The value of the setting fields. This allows modifying the values or applying defaults and such. Or taking info of the pipeline or analysis input object. When settings are not present in the onSubmit return value object, they are assumed to be not modified.
validationErrors
A list of AnalysisError essages representing validation errors. Submitting a pipeline execution request is not possible while there are still validation errors.
fieldId / FieldId
The field which has an erroneous value. When not present, a general error/warning is displayed. To display an error on the storage size, use the storageSizeFieldid.
index / Index
The 0-starting index of the value which is incorrect. Use this when a particular value of a multivalue field is not correct. When not present, the entire field is marked as erroneous. The value can also be an array of indexes for use with fieldgroups. For instance, when the 3rd field of the 2nd instance of a fieldgroup is erroneous, a value of [ 1 , 2 ] is used.
message / Message
The error/warning message to display.
context
"Initial"/"FieldChanged"/"Edited".
Initial is the value when first displaying the form when a user opens the start run screen.
The value is FieldChanged when a field with 'updateRenderOnChange'=true is changed by the user.
Edited (Not yet supported in ICA) is used when a form is displayed later again, this is intended for draft runs or when editing the form during reruns.
changedFieldId
The id of the field that changed and which triggered this onRender call. context will be FieldChanged. When the storage size is changed, the fieldId will be storageSize.
analysisSettings
The input form json as saved in the pipeline. This is the original json, without changes.
currentAnalysisSettings
The current input form json as rendered to the user. This can contain already applied changes form earlier onRender passes. Null in the first call, when context is Initial.
settingValues
The current value of all settings fields. This is a map with field id as key and an array of field values as value for multivalue fields. For convenience, values of single-value fields are present as the individual value and not as an array of length 1. In case of fieldGroups, the value can be multiple levels of arrays.
pipeline
Information about the pipeline: code, tenant, version, and description are all available in the pipeline object as string.
analysis
Information about this run: userReference, userName, and userTenant are all available in the analysis object as string.
storageSize
The storage size as chosen by the user. This will initially be null. StorageSize is an object containing an 'id' and 'name' property.
storageSizeOptions
The list of storage sizes available to the user when creating an analysis. Is a list of StorageSize objects containing an 'id' and 'name' property.
analysisSettings
The input form json with potential applied changes. The discovered changes will be applied in the UI.
settingValues
The current, potentially altered map of all setting values. These will be updated in the UI.
validationErrors
A list of RenderMessages representing validation errors. Submitting a pipeline execution request is not possible while there are still validation errors.
validationWarnings
A list of RenderMessages representing validation warnings. A user may choose to ignore these validation warnings and start the pipeline execution request.
storageSize
The suitable value for storageSize. Must be one of the options of input.storageSizeOptions. When absent or null, it is ignored.
fieldId / FieldId
The field which has an erroneous value. When not present, a general error/warning is displayed. To display an error on the storage size, use the storageSizeFieldid.
index / Index
The 0-starting index of the value which is incorrect. Use this when a particular value of a multivalue field is not correct. When not present, the entire field is marked as erroneous. The value can also be an array of indexes for use with fieldgroups. For instance, when the 3rd field of the 2nd instance of a fieldgroup is erroneous, a value of [ 1 , 2 ] is used.
message / Message
The error/warning message to display.
