Finding repeats in dna sequences

Question

[ojaswinipandey]

Hello,

I have a fasta file with dna sequences and need to find hexamer repeats across the sequences. I have been able to create hexamer substrings for each sequence given in the fasta file. But the out put is a separate list of substrings for each sequence. How do I put all the lists in one list (with replicates) to calculate the max frequency element.

Thanks, Regards

Can you provide sample input and desired output?
