4) Creating a FASTA file and reversing the sequence of it and printing it out in another FASTA file
My input file is TERT protein sequence, and its reverse output printed in "reverse_TERTseq.fasta":
---------------------------------------------------------------------------------------------------------------
- !/usr/bin/perl
use strict;
use warnings;
open(FILE, "<sequence.fasta") or die "Can't open the file: $_\n";
open(OUT, ">>reverse_TERTseq.fasta") or die "Can't open the filse: $_\n";
while (my $file = <FILE>){
$file = reverse $file;
print OUT "$file";
}
----------------------------------------------------------------------------------------------------------------
In another folder by name "sequence.fasta", I have saved TERT amino acid sequence:
>NP_937983.2 telomerase reverse transcriptase isoform 1 [Homo sapiens]
