CSV format requirements

General CSV format requirements

The following are the general format requirements for a CSV file used to create multiple cases:

1. The file must have a .csv extension.

2. The file must contain a [Data] header.

3. The row after [Data] header must include the field names identifying the data in each column. The column names are case-sensitive.

4. The row after the column name header and each subsequent row represents a sample.

5. Each column represents a data field.

6. It is essential that there are no empty rows between the [Data] header and the last sample row.

7. Number of cases per file can’t be greater than 50.

8. On versions before 34.0, cells should not contain commas. Consider replacing the commas with semicolons.

CSV schema

1. Mandatory fields

Must be present in the sample table at all times.

1. Case Type;

2. Family Id;

3. Phenotypes OR Phenotypes Id.

2. Conditionally mandatory fields

If these fields are left empty, it will result in the creation of an empty sample.

1. BioSample Name;

2. Files Names;

3. Storage Provider Id;

This field is mandatory if Files Names is empty:

1. Sample Type.

This field is required if the "auto" option is used for Files Names (only relevant for BSSH):

1. Default Project.

3. Optional fields

The sample table may include these supported optional columns.

1. Boost Genes;

2. Clinical Notes;

3. Date Of Birth;

4. Due Date;

5. Execute now;

6. Gender;

7. Gene List Id;

8. Kit Id;

9. Label Id;

10. Opt In;

11. Relation;

12. Selected Preset;

13. Visualization Files.

4. Custom fields

The sample table may contain custom columns to suit your specific needs and include any relevant information that is important for your workflow.

Each custom field must be assigned a unique name without spaces. Data from custom columns is saved per case under the Additional information section of Case Info.

Note: In cases with more than one sample, custom fields are only recognized and added to case information if their values appear within the same table row where the Relation field is equal to "proband".

Custom field examples:

Field (column) name	Expected input	Field details	Example
Institution	Free text	Custom	GenoMed Solutions
Sample_Received_Date	Free text	Custom	24-02-2022
Sample_Type	Free text	Custom	Amniotic Fluid

Batch case .csv file validation rules

Mandatory (highlighted in red), Conditionally mandatory (highlighted in orange), and Optional fields should be filled in according to the following rules.

Field (column) name	Expected input	Field details	Example
BioSample Name	Free text	Conditionally mandatory. An empty sample will be created if the field is left blank.	NA24385
Boost Genes	1. "TRUE" 2. "FALSE"	Optional. Indicates whether the Boost genes mode will be used. "TRUE" means that variants in the targeted genes will receive upgraded scores during prioritization by the AI Shortlist algorithm. Default value is "FALSE". Only considered for proband.	TRUE
Case Type	1. "Whole Genome" 2. "Exome" 3. "Custom Panel" 4. Custom case type	Mandatory. Only considered for proband.	Whole Genome
Clinical Notes	Free text	Optional	A 14-year-old boy with a visual acuity of 20/200 in both eyes in whom hearing loss was first noted at 5 years of age on routine screening; audiometry revealed sensorineural hearing loss.
Date Of Birth	Date "YYYY-MM-DD"	Optional	2013-01-22
Default Project	Free text	Conditionally mandatory. Must be filled in if the "auto" option is used for Files Names (only relevant for BSSH).	GIAB
Due Date	Date "YYYY-MM-DD"	Optional	2023-05-03
Execute now	1. "TRUE" 2. "FALSE"	Optional. Default value is "TRUE". Use "FALSE" if you don’t want to run the case upon uploading the file.e Only considered for proband.	FALSE
Family Id	Free text	Mandatory	RM8392
Files Names	1. Semicolon-separated list of paths to .fastq, .fastq.gz, .vcf, .vcf.gz, .bam, .cram files without spaces 2. "existing" 3. "auto"	Conditionally mandatory. An empty sample will be created if the field is left blank. The "existing" option automatically locates FASTQ files based on the BioSample Name. Note: If data files for an existing case were sourced from the customer’s external bucket and later removed, attempting to create a case from those files will result in an error. With the "auto" option, BSSH users can automatically locate FASTQ files based on the BioSample Name and Default Project provided. When using BSSH without the "auto" option, ensure that your file path is formatted correctly.	/GIAB_cases/1/NA24385.dragen.hard-filtered.gvcf.gz;/QA_cases/Other/NA24385.dragen.cnv.vcf.gz;/QA_cases/Other/NA24385.dragen.repeats.vcf;
Sex / Gender*	1. "F" 2. "M" 3. "U"	Optional. Default value is "U". *The field is labeled as Sex in versions 33.0 and later, and as Gender in older versions.	M
Gene List Id	integer	Optional. Must be the id of a previously defined Gene List. Only considered for proband.	12345
Kit Id	integer	Optional. Must be the id of a previously defined Kit. Only considered for proband.	23456
Label Id	integer	Optional. Must be the id of a previously defined Case Label. Only considered for proband.	34567
Opt In	1. "TRUE" 2. "FALSE"	Optional. Indicates whether the case subject consented to the extended sharing of data with your network(s). Default value is "TRUE".	FALSE
Phenotypes	Semicolon-separated list of HPO phenotype terms "Unaffected" is used for non-affected family members.	Mandatory for proband sample if Phenotypes Id is empty. List must be under 100. It is possible to include non-HPO terms if Phenotypes Id is empty.	Abnormal pupillary function;Orthotopic os odontoideum;
Phenotypes Id	Semicolon-separated list of HPO phenotype IDs	Mandatory for proband sample if Phenotypes is empty. List must be under 100.	HP:0007686;HP:0025375;
Relation	1. "proband" 2. "mother" 3. "father" 4. "sibling"	Optional. Default value is "proband". Values "proband", "father", "mother" can be only used once per Family ID. One sample with Relation "proband" is required per Family ID.	Mother
Sample Type	1. "FASTQ" 2. "VCF"	Conditionally mandatory. Required if Files Names is empty. Only considered for proband.	FASTQ
Selected Preset	1. Free text 2. "Default"	Optional. Must be the name of a previously defined Preset. If set to default, the default Preset will be applied. If left empty, no Preset will be applied.	High quality candidates

*Required BSSH file path format:

For BSSH, it is necessary to use the actual names (numbers):

/projects/3824821/appresults/2319318/files/119675608

instead of aliases

/projects/ABC_DEF_2022-12-22_DEv395/appresults/ABC-GM58342-def/files/ABC-GM58342-def.hard-filtered.vcf.gz
