Re: I can't access clustalw from my cgi perl program...

Yes, I've seen in that directory, but it doesn't exist. Another wierd thing
which is being happening is that If I make this output file manually in that
directory, it is read by the following code and printed on screen

if ("out.aln.pfam"){
	open FH, "out.aln.pfam" || die "Alignment file doesn't exist</br>";
	while(<FH>){

	print $_,"</br>";
	}
	close FH;
}

only when this code is not followed by the original code. When its followed by
the original code i.e.

my  $in  = Bio::AlignIO->new(-file   => $file1 ,
				-format => 'fasta');
	my $out = Bio::AlignIO->new(-file   => ">out.aln.pfam" ,
				-format => 'pfam');

	while ( my $aln1 = $in->next_aln() ) {
		$out->write_aln($aln1);
	}

	if ("out.aln.pfam"){
	open FH, "out.aln.pfam" || die "Alignment file doesn't exist</br>";
	while(<FH>){

	print $_,"</br>";
	}
	close FH;
	}

Nothing is printed on screen, while it stays there in the directory. I have
changed the name of output file in this code but new file is not produced by
this program. Does anyone know what is going on?

thanks
