Thank you so much for the effort, I haven't had a chance to look at your reply properly yet as I'm burning up with fever so probably not the best time to try and concentrate on scripting.

My data files are plain text files files that contain text and numbers stored in matrices, they look like this:

#title line - (skipped it with $nextUnless)
#title line - (skipped it with $nextUnless)
1 2 3
4 5 6
7 8 9

they're not necessarily 5 lines long, this is an example. The actual matrices are much bigger, I think my biggest file is a 85x85 matrix.

What I want to do is perform some mathematical calculations on the combination of matrices $i and $j. Get the averages of those matrices, their deviation etc. I haven't included this bit of the code yet but (fingers crossed) it works.

So I want to calculate the deviation between all matrices from file $i and files $j. The end result would be i) another matrix but this time with the average values or ii) a single value, for the deviation. But like I said this bit of the code isn't shown here as I tried to keep it to a minimum - if I fail in opening and splitting them in columns then I won't be able to move on to the next bit anyway.

At this stage I was trying to print them for testing only.

Hopefully this clears things up a bit and I honestly hope you guys will continue giving me feedback as I'm beyond stuck. Now off to read all answers from the top and hopefully understand what I've been messing up.

This website is an immensely helpful resource, thank you everyone. I sure wish one day I'll know enough to help others with their scripting problems :D
