I have several hundred files that look like this:
a.file #genomic positions 1, 3, 4, 9, 10 #factors a, b, d, g
Each file holds multiple genomic positions (numbers) and factors (characters). I want to investigate, whether there are genomic positions that frequently co-occur with factors across all files, but I have no idea on how to approach this. Can someone point me into the right direction? Is there a tool or a library that might help? Thank you!
