# ICA Manual Launch

### How to Launch a Manual Analysis <a href="#how-to-launch-analysis" id="how-to-launch-analysis"></a>

1. **Create a Project:** A project can be specific for the DRAGEN Spatial Transcriptome pipeline, or it can contain multiple pipelines and/or tools. For information on creating projects, refer to the Projects section in [Illumina Connected Analytics help](https://help.ica.illumina.com/home/h-projects).

ICA standard storage is used by default as soon as the project is saved. To connect a different storage source, set it up before creating your project. For details and options, refer to the Storage section in [Illumina Connected Analytics help](http://help.ica.illumina.com/home/h-storage).

1. **Upload the sequencing data:** For information on viewing and uploading data, refer to the Data section in [Illumina Connected Analytics help](https://help.ica.illumina.com/project/p-data).
2. **Start Analysis:** In the project, navigate to Pipelines, select the DRAGEN Spatial Transcriptome Pipeline, and then select "Start analysis". Set up the new analysis by configuring the parameters listed in the [table below](#analysis-parameters-on-ica). When the required files are complete, start the analysis.
3. **Review Results:** After analysis is complete, navigate to results in the configured output location.

Please see the Illumina Support Shorts for guidance on how to set up and run DRAGEN Spatial Transcriptome analysis on ICA.

### Analysis Parameters on ICA <a href="#analysis-parameters-on-ica" id="analysis-parameters-on-ica"></a>

| ------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Output BAM                      | `none` produces no output; `bam` outputs a BAM file. Note: generating BAM alignments will increase compute time and cost. Default: `none`.                                                                                                                                                                                                                                         |
| Include Intronic Reads          | By default, reads mapping to intronic regions are filtered out. Enable to include intronic reads in the analysis for capturing unspliced transcripts. See [Exonic and Intronic Alignments](/dragen-stratamap/dragen-spatial-transcriptome/analysis-methods.md#id-1-exonic-and-intronic-alignments) for details. Default: `False`.                                                  |
| Use only uniquely aligned reads | When enabled, only reads that uniquely align to the genome are used for analysis; multimapping reads are excluded. By default, multimappers are included by prioritizing alignments to protein-coding genes over non-protein coding genes. See [Multimapping](/dragen-stratamap/dragen-spatial-transcriptome/analysis-methods.md#id-2-multimapping) for details. Default: `False`. |

#### Cell Segmentation Parameters (all optional)

| Parameter Name                   | Description                                                                                                                                                                                                                                                                                                                           |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Output Nuclei Binned Results     | Enable to include analysis on nuclei-binned data. Note: full analysis will run on nuclei-binned data, increasing compute time and the size of the output folder. See [Cell and Grid Binning](/dragen-stratamap/dragen-spatial-transcriptome/analysis-methods.md#h-cell-and-grid-binning) for background on binning. Default: `False`. |
| Cell Boundary Expansion Distance | Sets the distance used to expand the nucleus boundary to determine the cell boundary. See [Cell Segmentation](/dragen-stratamap/dragen-spatial-transcriptome/analysis-methods.md#g-cell-segmentation) for details on how expansion works. The default and recommended setting is 5µm.                                                 |

#### Tertiary Analysis (all optional)

| Parameter Name | Description                                                                                                                                                                                                                                                                                                                                            |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Grid Bin Size  | <p>Enter a colon-delimited list of integers to submit additional grid bin sizes in addition to the default of 10µm. Analysis will run on each size, increasing compute time and cost. We do not recommend 3µm or smaller bin sizes. See <a href="/pages/tdCxd5DEszX8UnZxLDy0#id-1-grid-binning">Grid Binning</a> for details.</p><p>Default: 10µm.</p> |
| Skip Tertiary  | Skip PCA, UMAP, and clustering analysis steps to shorten runtime. See [Tertiary Analysis](/dragen-stratamap/dragen-spatial-transcriptome/analysis-methods.md#j-tertiary-analysis) for the steps that are skipped. Default: `False`.                                                                                                                    |

### Imageless Analysis on ICA

For workflows without microscopy images, the DRAGEN Spatial Transcriptome uses the SampleLocator feature to automatically detect sample regions. To run an imageless analysis, use the Imageless DRAGEN Spatial Transcriptome pipeline provided in the DRAGEN Spatial Transcriptome Bundle.

#### How Imageless Mode Works

SampleLocator analyzes sequencing data against the map file to automatically identify and segment tissue regions without requiring microscopy images.

### Data Transfer to Whitelisted Domain and Workgroup

If data is streamed to the incorrect domain (e.g. public or non-whitelisted domain) and is inaccessible in ICA, use the following instructions to transfer data to the correct, whitelisted private domain and workgroup using the BaseSpace Sequence Hub command line interface (BSSH CLI) tool.

These instructions will require you to perform the BSSH CLI tool installation and have your browser open to the intended domain and workgroup while you use a terminal to authenticate the Workgroup.

{% hint style="info" %}
Note: Items that are \[bracketed] require user input.
{% endhint %}

1. Install the BSSH CLI tool onto the device where runs are saved locally according to the instructions found here: [BSSH CLI Installation Instructions](https://developer.basespace.illumina.com/docs/content/documentation/cli/cli-overview)
2. In a browser, enter your private BSSH domain URL and log in.
   1. example: https\://\[private domain name].basespace.illumina.com/dashboard
3. Select the whitelisted Workgroup you intend to use and leave your browser open while you move to the next step.
4. Open a terminal and enter the following commands to authenticate your whitelisted Workgroup:
   1. Authenticate

      `bs auth -c [private domain name] --api-server https://api.basespace.illumina.com`
   2. Confirm authentication

      `bs -c [private domain name] whoami`
   3. If authenticated, the result should look like this with the Workgroup listed under "Name":

      INSERT SCREENSHOT HERE
5. Use the following command to send run data to your authenticated Workgroup:

   `[location of BSSH CLI] --config [private domain name] run upload --instrument=[NovaSeqX] --name=[run name] --retry [location of run]`
