Analysis of Chromosome Conformation Capture data (Hi-C)
Define where the pipeline should find input data and save output data.
Path to comma-separated file containing information about the samples in the experiment.
string^\S+\.csv$You will need to create a design file with information about the samples in your experiment before running the pipeline. Use this parameter to specify its location. It has to be a comma-separated file with 3 columns, and a header row. See usage docs.
The output directory where the results will be saved. You have to use absolute paths to storage on Cloud infrastructure.
stringEmail address for completion summary.
string^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$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.
MultiQC report title. Printed as page header, used for filename if not otherwise specified.
stringReference genome related files and options required for the workflow.
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.
Path to FASTA genome file.
string^\S+\.fn?s?a(sta)?(\.gz)?$This parameter is mandatory if --genome is not specified. If you don't have a BWA index available this will be generated for you automatically. Combine with --save_reference to save BWA index for future runs.
Directory / URL base for iGenomes references.
strings3://ngi-igenomes/igenomesDo 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.

stringParameters for protocols based on restriction enzyme
Name of restriction enzyme to automatically set the restriction_site and ligation_site options (hindiii, mboi, dpnii, arima)
stringRestriction motifs used during digestion. Several motifs (comma separated) can be provided.
stringExpected motif after DNA ligation. Several motifs (comma separated) can be provided.
stringFull path to file specifying chromosome sizes (tab separated with chromosome name and size)`.
stringIf not specified, the pipeline will build this file from the reference genome file
Full path to restriction fragment (bed) file.
stringThis file depends on the Hi-C protocols and digestion strategy. If not provided, the pipeline will build it using the --restriction_site option
If generated by the pipeline save the annotation and indexes in the results directory.
booleanUse this parameter to save all annotations to your results folder. These can then be used for future pipeline runs, reducing processing times.

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.
