Editorial: New perspectives for BiR with a new year

EDITORIAL EDITORIAL

Welcoming BiR into a new year full of goals, new developments, and achievements. This year’s resolution of BiR is to take this endeavor to a brand new platform of international standard and reputation necessary for spreading the knowledge of bioinformatics.

Dr. Muniba Faiza

Founding Editor

As bioinformatics is growing and gaining more and more interest in biological research, it has become an essential field in the last few years. Researchers are capable of tracking evolutionary history, designing new drugs, study the nature of organisms, and so on. Keeping that in mind, this year BiR is going to focus on advanced research in bioinformatics. BiR is hoping to organize internship programs and conferences to reach out to experts in bioinformatics. Besides, new tutorials will be provided both written and video tutorials as per the suggestions of our readers and subscribers. In this aspect, BiR thus seeks viewpoints and suggestions from all the readers. We would greatly appreciate that! We wish for a number of contributions from our readers in the form of articles or questions, and feedback to further improve the science reporting. With the support of our readers, we can easily move further. BiR is thankful to all of you and wishes you a very happy new year with great success ahead. Please share your thoughts at info@bioinformaticsreview.com.

“The script provided in this article can also be used for large files consisting of multiple FASTA sequences split into the indefinite number of residues per line.� ere is a simple Perl script to concatenate multiline FASTA sequences into a single line. A similar Perl script has been provided in one of the previous articles (A Perl script to convert multiline FASTA sequences into a single line). That script is useful for the FASTA files consisting of sequences split into a particular number of residues per line. The script provided in this article can also be used for large files consisting of multiple FASTA sequences split into the indefinite number of residues per line.

H

#!/usr/bin/perl -w use strict; my $input_fasta="input.fa"; open(FILE,"<$input_fasta ") || die ("Error opening $input_fasta $!"); my $line = ; print $line; while ($line = ) { chomp $line; if ($line=~m/^>;(.*)/) { print "\n",$line,"\n"; } else { print $line; } } print "\n"; exit;

Let's name the multiline FASTA input file as "input.fa". atoms only otherwise it will be giving errors.
