Pipeline to fetch metadata and raw FastQ files from public databases
1.4). The latest
stable release is
1.12.0
.
Define where the pipeline should find input data and save output data.
File containing SRA/ENA/DDBJ/GEO identifiers one per line to download their associated metadata and FastQ files.
string^\S+\.txt$Specifies the type of identifier provided via --input - available options are 'sra' and 'synapse'.
stringComma-separated list of ENA metadata fields to fetch before downloading data.
stringThe default list of fields used by the pipeline can be found at the top of the bin/sra_ids_to_runinfo.py script within the pipeline repo. This pipeline requires a minimal set of fields to download FastQ files i.e. 'run_accession,experiment_accession,library_layout,fastq_ftp,fastq_md5'. Full list of accepted metadata fields can be obtained from the ENA API.
Comma-separated list of ENA metadata fields used to create a separate 'id_mappings.csv' and 'multiqc_config.yml' with selected fields that can be used to rename samples in general and in MultiQC.
stringexperiment_accession,run_accession,sample_accession,experiment_alias,run_alias,sample_alias,experiment_title,sample_title,sample_description,descriptionName of supported nf-core pipeline e.g. 'rnaseq'. A samplesheet for direct use with the pipeline will be created with the appropriate columns.
stringForce download FastQ files via sra-tools instead of via the ENA FTP.
booleanOnly download metadata for public data database ids and don't download the FastQ files.
booleanPath to the output directory where the results will be saved.
string./resultsEmail address for completion summary.
string^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$Set this parameter to your e-mail address to get a summary e-mail with details of the run sent to you when the workflow exits. If set in your user config file (~/.nextflow/config) then you don't need to specify this on the command line for every run.
Path to Synapse configuration file
stringParameters used to describe centralised config profiles. These should not be edited.
Git commit id for Institutional configs.
stringmasterBase directory for Institutional configs.
stringhttps://raw.githubusercontent.com/nf-core/configs/masterIf you're running offline, Nextflow will not be able to fetch the institutional config files from the internet. If you don't need them, then this is not a problem. If you do need them, you should download the files from the repo and tell Nextflow where to find them with this parameter.
Institutional config name.
stringInstitutional config description.
stringInstitutional config contact information.
stringInstitutional config URL link.
stringSet the top limit for requested resources for any single job.
Maximum number of CPUs that can be requested for any single job.
integer16Use to set an upper-limit for the CPU requirement for each process. Should be an integer e.g. --max_cpus 1
Maximum amount of memory that can be requested for any single job.
string128.GB^\d+(\.\d+)?\.?\s*(K|M|G|T)?B$Use to set an upper-limit for the memory requirement for each process. Should be a string in the format integer-unit e.g. --max_memory '8.GB'
Maximum amount of time that can be requested for any single job.
string240.h^(\d+\.?\s*(s|m|h|day)\s*)+$Use to set an upper-limit for the time requirement for each process. Should be a string in the format integer-unit e.g. --max_time '2.h'
Less common options for the pipeline, typically set in a config file.
Display help text.
booleanMethod used to save pipeline results to output directory.
stringThe Nextflow publishDir option specifies which intermediate files should be saved to the output directory. This option tells the pipeline what method should be used to move these files. See Nextflow docs for details.
Email address for completion summary, only when pipeline fails.
string^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$An email address to send a summary email to when the pipeline is completed - ONLY sent if the pipeline does not exit successfully.
Send plain-text email instead of HTML.
booleanDo not use coloured log outputs.
booleanDirectory to keep pipeline Nextflow logs and reports.
string${params.outdir}/pipeline_infoBoolean whether to validate parameters against the schema at runtime
booleantrueShow all params when using --help
booleanRun this workflow with Conda. You can also use '-profile conda' instead of providing this parameter.
