How do you make the getline function return to the original line?
The example below should make it clear where I am currently going wrong.

GLAM2-PURGE(1) glam2 Manual GLAM2-PURGE(1) NAME
glam2-purge - Removes redundant sequences from a FASTA file SYNOPSIS
glam2-purge file score [options] DESCRIPTION
glam2-purge is a modified version of Andrew Neuwald's purge program that removes redundant sequences from a FASTA file. This is recommended in order to prevent highly similar sequences distorting the search for motifs. Purge works with either DNA or protein sequences and creates an output file such that no two sequences have a (gapless) local alignment score greater than a threshold specified by the user. The output file is named <file>.<score>. The alignment score is based on the BLOSUM62 matrix for proteins, and on a +5/-1 scoring scheme for DNA. Purge can also be used to mask tandem repeats. It uses the XNU program for this purpose. OPTIONS
-n Sequences are DNA (default: protein). -b Use blast heuristic method (default for protein). -e Use an exhaustive method (default for DNA). -q Keep first sequence in the set. -x Use xnu to mask protein tandem repeats. SEE ALSO
glam2(1), glam2format(1), glam2mask(1), glam2scan(1), xnu(1) The full Hypertext documentation of GLAM2 is available online at http://bioinformatics.org.au/glam2/ or on this computer in /usr/share/doc/glam2/. REFERENCES
