I think you'll have a problem with the argument structure:
sub revdnacomp { # my $dna = @_; # the above means $dna gets the number of # arguments in @_, since it's a scalar context! my $dna = shift; # or my $dna = shift @_; # ah, scalar context of scalar gives expected results. # my ($dna) = @_; # would work, too my $revcomp = reverse($dna); $revcomp =~ tr/ACGTacgt/TGCAtgca/; return $revcomp; }
but why not allow the complementation over more than one element?
sub revcompl { # operates on all elements passed in my (@dna) = @_; foreach my $segment (@dna) { my $revcomp = reverse($segment); $revcomp =~ tr/ACGTacgt/TGCAtgca/; push @done, $revcomp; } return @done; # or reverse @done; # what's best semantics? }
Did I miss anything?
