When greping for positions of interest, I noticed that my pileup file seems to contain a number of lines that repeat chromosome number and position, like this:
From a pileup of a total of 15980465 lines, I get 10346 not-unique positions (chr + position).
Is this normal? If yes, why does this happen? And if not, what might be the reason?
Many thanks in advance for your comments.
