Dear All, I just begin to learn perl to solve some biology problem. I have a matrix(rows400*columns4000), I only want to print out a new matrix which have all rows but part of the columns like: 1,2,3,5,9,10,38,..126,....,(around 1660 columns) those columns distribute no rules at all. How can I get into it? Please help and Thanks advance!
