Thank you very much Brent!

As you suspected I am a biologist and I thought I'd see what Perl has to offer. Thanks for such a comprehensive and detailed piece of code, I really appreciate your time and effort. Out of interest, could the "foreach (1 .. 10)" loop be modified to accommodate variation in the number of data lines? something like:

foreach (integer),else exit loop

Cheers!
