Re^12: Help with pushing into a hash

    Hey there kenosis. Sorry to bother you again. SO the program is no longer giving me error messages, but the pushing to the arrays here:

    push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1}; push @antioxline, "$1 | $2 | $antiox{$1} \n" if $antiox{$1}; push @toxinline, "$1 | $2 | $toxin{$1} \n" if $toxin{$1};

    isn't working properly. For example I selected a specific number from $activin, which was in $uniprot, but it wasn't in the final output. So @activline, @antioxline and @toxinline are much smaller than they should be. So a lot of the data that is supposed to be in the output is not there anymore. I tried testing with this:

    if ($1 eq "E7F888"){print $2;}

    and it gave me the correct $2, I tried this too:

    next unless /(E7F888)\s+.+=([^\s]+)/; push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1}; print @activline;

    and it printed the correct thing. But if I removed the tests i put, and ran the normal code, E7F888 is not in @activline. Is there anything I could do to figure out what's wrong with my code? Here's it again.

    #!/usr/bin/perl use Modern::Perl; use File::Slurp qw/read_file write_file/; my $uniprot = 'uniprot-ACN'; my $activin = 'Activator-PFAM.txt'; my $antioxin = 'AntiOxidant-PFAM.txt'; my $toxinin= 'Toxin-PFAM.txt'; my $activout = 'ActivACNPF.txt'; my $antioxout= 'AntioxACNPF.txt'; my $toxinout= 'ToxinACNPF.txt'; my @activline; my @antioxline; my @toxinline; my %activ = map {s/\.\d+//g; /(.+)\s+\|\s+(.+)/ and $1 => $2 } grep / +\|\s+\S+/, read_file $activin; my %antiox = map { s/\.\d+//g; /(.+)\s+\|\s+(.+)/ and $1=>$2; } grep/\ +|\s+\S+/,read_file $antioxin; my %toxin = map { s/\.\d+//g; /(.+)\s+\|\s+(.+)/ and $1=>$2; } grep/\ +|\s+\S+/,read_file $toxinin; #if (exists $activ{"E7F888"}) { #print $activ{'E7F888'};} #else {print "LOL";} for ( read_file $uniprot ) { next unless /(.{6})\s+.+=([^\s]+)/; # if ($1 eq "E7F888"){print $2;} push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1}; push @antioxline, "$1 | $2 | $antiox{$1} \n" if $antiox{$1}; push @toxinline, "$1 | $2 | $toxin{$1} \n" if $toxin{$1}; } print @activline; write_file $activout, @activline; write_file $antioxout, @antioxline; write_file $toxinout, @toxinline;

    THanks so much.

      Hi, jemswira!

      This is no bother at all!

      You mentioned that the following captured a key that wasn't in the final set:

      next unless /(E7F888)\s+.+=([^\s]+)/; push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1}; print @activline;

      Try the following:

      next unless /(E7F888)\s+.+=([^\s]+)/; say; exit;

      saywill print the scalar $_ which the regex operates on. By doing this, you can examine the line to verify that the matches the following regex:

      /(.{6})\s+.+=([^\s]+)/

      Also, it may be that the 'key' is not being captured from $activin, since:

      push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1};

      will work only if the 'key' if found in both files and the regexs which process both work as they should.

      Let me know what you find...

        well i ran the code and it returned this:

        E7F888 Name=arid5b ;PF01388

        which is correct. Well I selected the number cause it was in both files ( I manually ctrl-f ed the notepad file.

        Well a lot of lines are missing from the final output. The $activ is 512 kb large and the out put is 3kb. And also @activline is missing alot when I did print @activline;. I randomly selected E7F888 from $activin and checked to make sure it was in $uniprot, so it may be another offending line of data. If I did this:

        print $activ{E7F888},"\n"; for ( read_file $uniprot ) { next unless /(E7F888)\s+.+=([^\s]+)/; say; push @activline, "$1 | $2 | $activ{$1} \n" if $activ{$1}; } print @activline; } print @activline;

        I got this:

        PF01388 E7F888 Name=arid5b ;PF01388 E7F888 | arid5b | PF01388

        which showed that it was in %activ and that it was found in the file. But when I run through the normal code, it is not in @activ anymore.

        UPDATE,

        I ran the following code to check something, and not all the data is printed, I.E. A lot of lines are not pushed into the array.

        #!/usr/bin/perl use Modern::Perl; use File::Slurp qw/read_file write_file/; my $uniprot = 'uniprot-sfinal.txt'; my $activin = 'Activator-PFAM.txt'; my %activ = map { s/\.\d+//g; /(.+)\s+\|\s+(.+)/ and $1=>$2; } grep/\| +\s+\S+/,read_file $activin; for ( read_file $uniprot ) { next unless /(.{6})\s+.+=([^\s]+)/; print $1,"\n" if $activ{$1}; } print "done";

        I am sure that there are more lines that are supposed to be printed. E.G.

        $uniprot: Q801F8 Q90XZ5; Q90XZ8;Name=dmrt1 B7ZS42 A4PBN7; B7ZS44;Name=dmrt1-b ;PF00751;PF12374 Q157S1 Name=Crtc1 Synonyms=Mect1, $activ: Q801F8 | PF00751.13 PF12374.3 PF12374.3 B7ZS42 | PF00751.13 PF12374.3 PF12374.3 Q157S1 | PF12886.2 PF12885.2 PF12884.2

        I shall try to reverse the order, I.E, make a hash out of $uniprot instead of $activ and run it again.
