jemswira has asked for the wisdom of the Perl Monks concerning the following question:
So I recently posted up this code on perlmonks asking for help, and got it to work properly(THANKS)
$/="\/\/"; our @acnumbers=qw(P0A252 Q9AT80 Q0HKB6); our $acnumbers; foreach $acnumbers(@acnumbers){ my $unit; foreach $unit(<PFAMDB>){ my @units= split /#/,$unit; my @pfx=grep(/=GF AC/,@units); our $units; foreach $units(@units){ if ($units=~/.*AC $acnumbers/){ push (@list, @pfx); }else{next} } } print "$acnumbers is in:"; print @list; undef @list; }
So what it did was to take this data
# STOCKHOLM 1.0
#=GF ID 1-cysPrx_C
#=GF AC PF10417.4
#=GF DE C-terminal domain of 1-Cys peroxiredoxin
...
#=GS D8BPP0_ECOLX/154-186 AC D8BPP0.1
#=GS D6I5T0_ECOLX/154-186 AC D6I5T0.1
...
//
...
find the PFxxxx number and whether the AC xxxxxx number was in it.
There's another file, which has many lines of:
>tr|A0A171|A0A171_PYRHR Glutamate synthase small subunit-like protein 1 OS=Pyrococcus horikoshii GN=gltY PE=4 SV=1
and i need to get the A0A171, and A0A171_PYRHR Glutamate synthase small subunit-like protein 1 out also, then run the first code. So i got this:
foreach (<DATABASE>){push (@uniprot,$_);} my $i; my $name; foreach $uniprot(@uniprot){ our $acc; my @splitted=split /\||=/,$uniprot; foreach $i(@splitted){ if ($i=~/\b\w{6}\b/ and $i !~/\_/){ $acc=$i; } elsif ($i=~ /.+(?= OS)/){ $name=$i; } else {next;} my $unit; $/="\/\/"; open PFAMDB, 'C:\Users\Jems\Desktop\Perl\PFAM.txt' or die $!; foreach $unit(<PFAMDB>){ my @units= split /#/,$unit; my @pfx=grep(/=GF AC/,@units); our $units; foreach $units(@units){ if ($units=~/.*AC $acc/){ push (@list, @pfx); }else{next} } } print "$acc, also called $name, is in:" print @list; undef @list; }}
however it no longer seems to get @list out. @pfx is still correct when i print tested, but it no longer pushes to @list. (I THINK)
so is it that i am doing anything wrong? also, how would i remove the OS at the back of $name, and the #=GF AC and everything after the fullstop in @pfx? Thanks in advance!
