in reply to Getting indices of the same value that occurs multiple times in an array...

I can see some answers have been supplied to solve the problem of entering the values into an Hash via a mapped grep. I have looked at the initial problem of identifying multiple values within each line. The aligned families can be retrieved using an array reading loop. However I caqn imagine further data manipulation would mean having the families in a hash may be more helpful in future reference. Here is how I would initially extract the multiple values via an array loop.

use strict; use warnings; my $gendata = './gen.dat'; open GENDAT, "< $gendata" or die "can't open $gendata $!"; my @count; while (<GENDAT>){ push @count, $_; } close GENDAT; my $a=shift @count; my @families=split(/\s+/,$a); my $b=0; foreach my $c(@count){ my @state; push @state, split(/\s+/,$c); print $state[0].' '; for($b=0;$b<=$#state;$b++){ print $families[$b].' ' if $state[$b] eq '1'; } print $/; } exit (0);

this gives:

OG_1 lacM mori OG_2 taba glyB

A different approach might be assigning values to each of the families and then extract the 01 strings and convert them into a binary then return the relevant family pair as determined by the binary value. Of course this would only work if there were a definite 2 unique families per 'OG'.

    Should cpanminus be part of the standard Perl release?
