A Tool for Multiplex Chromatin Interaction Analysis by Efficiently Sorting Chromatin Complexes

MIA-Sort: Multiplex Chromatin Interaction Analysis by Efficiently Sorting Chromatin Complexes

Installation

chmod +x ./bin/install.sh
./bin/install.sh
source env/bin/activate

Bedtools should also be installed. To do so, follow instructions on https://bedtools.readthedocs.io/en/latest/content/installation.html#. One of the options is:

$ mamba install -c conda-forge bedtools

Every line is independent from each other. We will only do one line at a time. Each line will be conducted in only 1 second.

Column 1 and 2 (0-indexed) indicate the range of left anchor (left reference) and Column 4 and 5 indicate the right anchor.

We will need right anchor even when we do left anchor because we only want to rank GEMs that meet the left anchor and also with the rightmost fragment that is less than the right anchor region.

GEMs (.PEanno)

chr10	101762606	101763188	2	SHG8033-100000080-AAACACCAGAGGGTAABX8033-HEA-5-2-sub-1-1	E
chr10	104102286	104102852	2	SHG8033-100000080-AAACACCAGAGGGTAABX8033-HEA-5-2-sub-1-1	E
chr10	88838102	88838730	2	SHG8033-100000171-AAACACCAGCGCCCTABX8033-HEA-4-0-sub-1-1	P

Every line represents a fragment. Column 1 (0-indexed) represents the left point and Column 2 represents the right point of the fragment.

Column 3 (0-indexed), in this case 2, indicates the number of fragments in one GEM/chromatin complex.

Each GEM has a unique id (Column 4), so you can see that line 1 and 2 have the same Column 4 since they are the two fragments in the same GEM.

Ignore the 6th column.
