I need to generate permutation of some words (A T G C ) actually nucleotides for di-composition (eg AA AT AG AC), tri-composition (AAA AAT AAC AAG), tetra, penta etc (one at a time) and then check in the other file that contains sequences with some values the count of occurrences of each permutation. I generated the permutation list. Now I need to loop through the sequences only (splitting the sequences from values) for counting each of the permutation...
