COOLTOOLS DOTS

https://img.shields.io/github/issues-pr/snakemake/snakemake-wrappers/bio/cooltools/dots?label=version%20update%20pull%20requests

Calculate cis eigenvectors for a resolution in an .mcool file

URL: https://github.com/open2c/cooltools

Example

This wrapper can be used in the following way:

rule cooltools_dots:
    input:
        cooler="small_test.mcool",  ## Multiresolution cooler file
        expected="test_expected.tsv",  ## Expected file
        view="test_view.txt",  ## File with the region names and coordinates
    output:
        "HFF_{resolution,[0-9]+}.dots.bedpe",
    params:
        extra="",  ## Add extra parameters
    threads: 4
    log:
        "logs/HFF_{resolution}_dots.log",
    wrapper:
        "v3.8.0-1-g149ef14/bio/cooltools/dots"

Note that input, output and log file paths can be chosen freely.

When running with

snakemake --use-conda

the software dependencies will be automatically deployed into an isolated environment before execution.

Software dependencies

  • cooltools=0.6.1

Input/Output

Input:

  • a multiresolution cooler file (.mcool)

  • an expected file

  • (optional) view, a bed-style file with region coordinates and names to use for analysis

Output:

  • A .bedpe file with coordinates of detected dots. Can have a {resolution} wildcard that specifies the resolution for the analysis, then it doesn’t need to be specified as a parameter.

Params

  • resolution: Optional, can be instead specified as a wildcard in the output

  • extra: Any additional arguments to pass
