How to print out a part of the line?

[Anja Friedrich]

Hi all,

I was wondering if it's possible to print out only a part of a line? The problem is I have an array with one motif in different variants, like this:
small_motif_a CGTCGCACAGC
small_motif_b CGTCGCACGAC
small_motif_c CGTCGCCCAGC
But in my output I only want the variant, without the nucleotide motif. Is that possible?
Like this: small_motif_a 811 821
(positions will be find by the script)

 
$pos= $pos + length($`)+1;
        $pos2= $pos + length($&)-1;
    print OUTFILE "$_\t $pos\t $pos2\n";
    $refseq= $';
        $temp=1;
        $found=$found+1;    
 

Cheers,
Anja

Yes, it is possible to only print part of a line, and there are various ways to do so. One way is to use split as follows:

use strict;
use warnings;
 
while (<DATA>) {
    my $motif = (split)[0];
    print "$motif\n";
}
 
__DATA__
small_motif_a CGTCGCACAGC
small_motif_b CGTCGCACGAC
small_motif_c CGTCGCCCAGC
 

This prints out:

small_motif_a
small_motif_b
small_motif_c

I have no idea how you determine your position values. Can you elaborate?
