Output as .cool format instead of .mcool

[mb6434]

Hi,

Thank you very much for the development of this tool. I am facing an issue regarding the output format.

Here is the cmd line which I used:

HiCLift --input $file.cool --input-format cooler --out-pre test --output-format cool --out-chromsizes mm10_2.sizes --in-assembly mm9 --out-assembly mm10

I would like to know how could you got a .cool format instead of .mcool.

And also, I am not familiar with the argument --high-res, would you please develop a little bit?!

Thank you for your help and time,

Best regards,

Mathilde

Hi Mathilde,

.mcool is just an extension of .cool which stores contact matrices at multiple resolutions, and it's quite straightforward to extract the contact matrices at a specific resolution into a .cool file. Suppose your output .mcool file name is "test.mm10.mcool", and you want to extract the contact matrix at 5kb, just execute the cooler cp command below::

$ cooler cp test.mm10.mcool::resolutions/5000 test.mm10.5kb.cool

You can use the cooler ls command to list all individual cool files (cool URIs) within a .mcool file::

$ cooler ls test.mm10.mcool

By default, the highest resolution of contact matrices reported by HiCLift is 5kb. By specifying "--high-res", the highest reported resolution will be set to 1kb.

Best,
