Thanks monks, I think I have a piece of working code. I still get a few errors, but I think it is from inconsistencies in the datafile. I will post the final code below, and if someone finds more errors I will check back periodically.

#!/usr/bin/perl use strict; use warnings; # prints out inhibited object, directly activated ohjects, directly de +activated objects, indirectly activated objects, indirectly deacivate +d objects print "Modified Object\tActivated Objects\tDeactivated Objects\n"; open(DAT,'<',"./")||die "Canot open file\n"; my @file=<DAT>; close DAT; shift @file;##remove header my @activated; my @inhibited; my %true; foreach my $line(@file){ my @line=split(/\t/,$line); if($true{$line[0]}){ next;#if element has already come up, skip it } else{ $true{$line[0]}=1;#if object has already come up, store true } print "$line[0]\t";#inhibited object &inhibited_rec($line[0]); foreach(@activated){ print "$_,"; } print "\t"; foreach(@inhibited){ print "$_,"; } print "\n"; } sub inhibited_rec{ my @a=`awk '\$1 ~ /$_[0]/' |cut -f 2,3|sort|uniq`; foreach (@a){ my @b=split(/\t/,$_); chomp $b[1]; if($b[1] eq 'Activation'){ } else{ push (@activated,$b[0]); if($true{$b[0]}){ next; } else{ $true{$b[0]}=1; &activated_rec($b[0]); } } } } sub activated_rec{ my @a=`awk '\$1 ~ /$_[0]/' |cut -f 2,3|sort|uniq`; foreach (@a){ my @b=split(/\t/,$_); chomp $b[1]; if($b[1] eq 'Activation'){ push (@activated,$b[0]); if($true{$b[0]}){ next; } else{ $true{$b[0]}=1; &activated_rec($b[0]); } } else{ push (@inhibited,$b[0]); if($true{$b[0]}){ next; } else{ $true{$b[0]}=1; &inhibited_rec($b[0]); } } } }
