common coordinates from 10 files

Question

[K]

Hi,

I have 10 files and I am interested to find all the common coordinates occurred in all to manipulate a synteny plot. Is there a way either script or program which I can use?

I know comm and diff command for two files.

Thank you

Couldn't you use a bash for loop and comm -3 to spit out the common portion between each file and the last comm -3 result, to get what must be common between all the files? Any element in common in all the files will always survive the comparison. Assuming all the files are sorted (you can add a sort step), something like:

#!/bin/bash
FILES="file1
file2
file3"

# create a first file
cp file1 common.txt

for f in $FILES
do
    echo "processing: $f"
    comm -3 $f common.txt > common.txt
done

Otherwise I would imagine a similar strategy with bedtools intersect might work.

I am looking something like venn diagram analysis where I can see unique coordinates in each scaffold file and common in each subset. I saw some online tools where the datasets in limited to 3 input files but I want to know interactions between 10 scaffolds?

if your files are tsv file and can make one file as reference, you can try:

$ tsv-join -f filter.tsv -k 2,3  data1.tsv data2.tsv data3.tsv

download tsv-utils from here and 2,3 are common columns among the files. Filter.tsv is reference file and rest of the files are files to be joined. Always post representative, example data if you want forum members to understand your query better.
