Hello,

One more approach with sed may help.

Code:
sed 's/\(^>.*_\)\(.*\)/my_desired_text_\2/g' file_name

Output will be as follows.

Code:
my_desired_text_45
atatagcaga
my_desired_text_46
atatagcagaatatatat



Thanks,
R. Singh

One more approach for same as follows.


Code:
awk -vs1="my_desired_ouput_" -F"_" '/^>/ {print s1$NF} !/^>/' file

Output will be as follows.

Code:
my_desired_ouput_45
atatagcaga
my_desired_ouput_46
atatagcagaatatatat


Thanks,

GLAM2FORMAT(1)							   glam2 Manual 						    GLAM2FORMAT(1)

NAME
glam2format - converts GLAM2 motifs to FASTA or MSF format SYNOPSIS
glam2format [options] my_format my_motif.glam2 Formats: fasta, msf. DESCRIPTION
glam2format reads in a motif found by glam2, and writes it in a standard alignment format (FASTA-with-gaps or MSF). This enables the alignment to be passed to third-party software, including graphical visualization tools such as Kalignvu, Boxshade, and WebLogo. On the other hand, not all the motif information is preserved: in particular, the key positions are lost. Only the top motif in glam2 output is converted. OPTIONS (DEFAULT SETTINGS) -o Output file (stdout). -c Make a compact alignment. By default, residues that are inserted between key positions are written as unaligned with each other. This best reflects glam2's intention, but it can make the alignment large and full of gaps. With -c, inserted residues are written as arbitrarily aligned with each other, just as they appear in the glam2 output. -f Sequence file to make a "global" alignment by adding flanking sequences from the original FASTA-format sequence file. The flanking sequences will be written as either unaligned with each other or arbitrarily aligned, depending on the -c option. The sequences should have unique names and their order should be unchanged. SEE ALSO
