Define where the pipeline should find input data and save output data.

File containing SRA/ENA/GEO/DDBJ identifiers one per line to download their associated metadata and FastQ files.

required
type: string
pattern: ^\S+\.(csv|tsv|txt)$

Comma-separated list of ENA metadata fields to fetch before downloading data.

type: string

The default list of fields used by the pipeline can be found at the top of the bin/sra_ids_to_runinfo.py script within the pipeline repo. This pipeline requires a minimal set of fields to download FastQ files i.e. 'run_accession,experiment_accession,library_layout,fastq_ftp,fastq_md5'. Full list of accepted metadata fields can be obtained from the ENA API.

Comma-separated list of ENA metadata fields used to create a separate 'id_mappings.csv' and 'multiqc_config.yml' with selected fields that can be used to rename samples in general and in MultiQC.

type: string
default: experiment_accession,run_accession,sample_accession,experiment_alias,run_alias,sample_alias,experiment_title,sample_title,sample_description

Name of supported nf-core pipeline e.g. 'rnaseq'. A samplesheet for direct use with the pipeline will be created with the appropriate columns.

type: string

Value for 'strandedness' entry added to samplesheet created when using '--nf_core_pipeline rnaseq'.

type: string
default: auto

The default is 'auto' which can be used with nf-core/rnaseq v3.10 onwards to auto-detect strandedness during the pipeline execution.

Method to download FastQ files. Available options are 'aspera', 'ftp' or 'sratools'. Default is 'ftp'.

type: string

FTP and Aspera CLI download FastQ files directly from the ENA FTP whereas sratools uses sra-tools to download *.sra files and convert to FastQ.

Only download metadata for public data database ids and don't download the FastQ files.

type: boolean

dbGaP repository key.

type: string

Path to a JWT cart file used to access protected dbGAP data on SRA using the sra-toolkit. Users with granted access to controlled data can download the JWT cart file for the study from the SRA Run Selector upon logging in. The JWT file can only be used on cloud platforms and is valid for 1 hour upon creation.

The output directory where the results will be saved. You have to use absolute paths to storage on Cloud infrastructure.
