Let me format this for you, with some recoding as well.


This probably won't work for you since I wasn't sure what your input data looked like. My assumption was that it was multi-space delimited, but as I re-read your spec, it might have the actual labels interspersed in there.

Perhaps you could include some sample data to clear this up?

use strict; use warnings; use autodie; my $length; my $file = 'the filename...'; open(my $fh, '<', $file) || die "cant open file\n"; while (<$fh>) { chomp; my($target, $mirna, $score, $start) = split(/\s+/); print join("\t", $mirna, $target, $start, $score), "\n"; $length = $.; } close $fh;

This is the code i have written for which the output is:

miR156a AT3G19833 151 0.607541 miR156a AT3G19883 11 0.607541 miR156a AT3G19883 12 0.607541 miR156a AT3G19773 15 0.607541 miR156a AT3G19833 161 0.607541 miR156a AT3G19780 163 0.607541

I haven't tested this, and this might not work exactly as you need it to, but I think it avoids some of the problems you might have had in your version.

[marto]: I doubt it even exists as a building site :P
[ambrus]: Corion: does building airports "somewhat outside of" a city ever work? cities always grow around the airport quickly, because it's practical to be close to it, and after that, people start to complain that the airplanes land so close to their house and sh
