My subroutine is following:

sub align {
	my $file=shift @_;
	my @params = ('ktuple' => 2,'matrix' => 'BLOSUM', 'output' => 'fasta',  
'outfile' => 'temp_align.out');
	my $factory = Bio::Tools::Run::Alignment::TCoffee->new(@params);
	my $aln=$factory->align ($file);
	open (fy,'temp_align.out'); my @temp_file=<fy>; close fy;
	return @temp_file;
}

This subroutine is called by the following command:

my @align_fa = align($inputfile_align);

After successful execution of this subroutine (accompaning with the  
corresponding messages on the terminal window) the execution of remainder  
script is terminated without any error messages.
