Thanks again almut!

I really appreciate your inputs.

I am trying to manipulate $_ to obtain the desired results. But when I split it with a newline the data-lines also split up. In this case, if a record holds more than one sequence data, the remaining records are not getting printed! 

while (<FASTA>)
    {
    s/^>//mg;
#    print "$_";
    my ($name) = /^([^\n]+)/;
    
    #my ($name) = /^([\w.]+)/;
      
    #print "$name\n";
        if($hash{$name} == 10){
        select FILE1;
        }
        if($hash{$name} == 20){
        select FILE2;
        }
        if($hash{$name} == 30){
        select FILE3;
        }
    #print ">$_";
    my $output = $_;
    my (@title) = split(/\n/,$output);
    print ">".$title[0]."\n".$title[1]."\n";
}

I am splitting it with a new line character, in order to print the complete header line in my output files (and I am going wrong here).

Please suggest?

Thanks!
