Define where the pipeline should find input data and save output data.
Input FastQ files.
stringUse this to specify the location of your input FastQ files. For example:
--input 'path/to/data/sample_*_{1,2}.fastq'
Please note the following requirements:
- The path must be enclosed in quotes
- The path must have at least one
*wildcard character - When using the pipeline with paired end data, the path must use
{1,2}notation to specify read pairs.
If left unspecified, a default pattern is used: data/*{1,2}.fastq.gz
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.
Options for the reference genome indices used to align reads.
Name of iGenomes reference.
stringIf using a reference genome configured in the pipeline using iGenomes, use this parameter to give the ID for the reference. This is then used to build the full paths for all required reference genome files e.g. --genome GRCh38.
See the nf-core website docs for more details.
Organism for small RNA reference.
stringPath to small RNA FASTA file
stringPath to genome FASTA file.
stringIf you have no genome reference available, the pipeline can build one using a FASTA file. This requires additional time and resources, so it's better to use a pre-build index if possible.
Path to genome FASTA index file
stringPath to GTF annotation file
stringPath to genome STAR index
stringSave STAR index if generated within pipeline.
booleanDirectory / URL base for iGenomes references.
strings3://ngi-igenomes/igenomes/Do not load the iGenomes reference config.
booleanDo not load igenomes.config when running the pipeline. You may choose this option if you observe clashes between custom parameters and those supplied in igenomes.config.

integer1000Less 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.
Boolean whether to validate parameters against the schema at runtime
booleantrueEmail address for completion summary, only when pipeline fails.
string^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$This works exactly as with --email, except emails are only sent if the workflow is not successful.
Send plain-text email instead of HTML.
booleanSet to receive plain-text e-mails instead of HTML formatted.
File size limit when attaching MultiQC reports to summary emails.
string25.MBIf file generated by pipeline exceeds the threshold, it will not be attached.
Do not use coloured log outputs.
booleanSet to disable colourful command line output and live life in monochrome.
Custom config file to supply to MultiQC.
stringDirectory to keep pipeline Nextflow logs and reports.
string${params.outdir}/pipeline_infoShow all params when using --help
booleanSet 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\.]+\s*.(K|M|G|T)?B$Use to set an upper-limit for the memory requirement for each process. Should be a string in the format integer-unit e.g. --max_memory '8.GB'
Maximum amount of time that can be requested for any single job.
string240.h^[\d\.]+\.*(s|m|h|d)$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'
Parameters used to describe centralised config profiles. These should not be edited.
Git commit id for Institutional configs.
stringmasterProvide git commit id for custom Institutional configs hosted at nf-core/configs. This was implemented for reproducibility purposes. Default: master.
## Download and use config file with following git commit id
--custom_config_version d52db660777c4bf36546ddb188ec530c3ada1b96
Base 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 the custom_config_base option. For example:
## Download and unzip the config files
cd /path/to/my/configs
wget https://github.com/nf-core/configs/archive/master.zip
unzip master.zip
## Run the pipeline
cd /path/to/my/data
nextflow run /path/to/pipeline/ --custom_config_base /path/to/my/configs/configs-master/
Note that the nf-core/tools helper package has a
downloadcommand to download all required pipeline files + singularity containers + institutional configs in one go for you, to make this process easier.
