Hi my dear perl-friends, I'm trying to extract data from a big datafile to create many small ones where there is only the data from 1 person left. My datafile is 3.4GB big so I have to proceed wisely. The format is like this: - 4variables, which should find their way in every new file - 9columns per person My goal is, that I'm having in the end x files (where x=Number of people) where in each file there are 13 columns. I just don't quite get my head around how I can code, that perl opens the "motherfile", prints columns 0-4 and 5-13 in one file; for the next file it would be columns 0-4 again and 14-22 and so on. If anyone of you wise guys out there has a solution, I would be veeeeeery grateful to hear about it. Thanks in advance
