Analysis of Chromosome Conformation Capture data (Hi-C)
1.3.0
). The latest
stable release is
2.1.0
.
Define where the pipeline should find input data and save output data.
Input FastQ files.
string
Use 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
Input FastQ files for test only
string
undefined
The output directory where the results will be saved.
string
./results
Email 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.
string
If 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
If 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.
Directory / URL base for iGenomes references.
string
s3://ngi-igenomes/igenomes
Do not load the iGenomes reference config.
boolean
Do 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
.
Full path to directory containing Bowtie index including base name. i.e. /path/to/index/base
.
string
Parameters for protocols based on restriction enzyme
Name of restriction enzyme to automatically set the restriction_site and ligation_site options
string
hindiii
Restriction motifs used during digestion. Several motifs (comma separated) can be provided.
string
'A^AGCTT'
Expected motif after DNA ligation. Several motifs (comma separated) can be provided.
string
'AAGCTAGCTT
Full path to file specifying chromosome sizes (tab separated with chromosome name and size)`.
string
If not specified, the pipeline will build this file from the reference genome file
Full path to restriction fragment (bed) file.
string
This 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.
boolean
Use this parameter to save all annotations to your results folder. These can then be used for future pipeline runs, reducing processing times.
Save the non valid pairs detected by HiC-Pro.
boolean
Use this parameter to save non valid pairs detected by HiC-Pro (dangling-end, self-circle, re-ligation, filtered).

Git commit id for Institutional configs.
string
master
Provide 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.
string
https://raw.githubusercontent.com/nf-core/configs/master
If 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
download
command to download all required pipeline files + singularity containers + institutional configs in one go for you, to make this process easier.
Institutional configs hostname.
string
Institutional config name
string
Institutional config description.
string
Institutional config contact information.
string
