Introduction

MView is a command line utility that extracts and reformats the results of a sequence database search or a multiple alignment, optionally adding HTML markup for web page layout. It can also be used as a filter to extract and convert searches or alignments to common formats.

Inputs:

• Sequence database search: BLAST, FASTA suites.
• Multiple sequence alignment: CLUSTAL, HSSP, MSF, FASTA, PIR, MAF.

Outputs:

• HTML, FASTA, CLUSTAL, MSF, PIR, RDB (tab-separated).

The tool is used in molecular biology and biomedical research for data analyses and as a component in various bioinformatics web services. Research papers citing MView are indexed on Google Scholar.

Manual

Full documentation can be found in the manual, a copy of which is bundled with the code.

Requirements

MView is implemented in Perl, version 5 as a self-contained command line program that should run cross-platform.

Perl is generally installed on Linux and UNIX systems. MView is known to work on Windows with Strawberry Perl.

Download

• The current release can be downloaded from SourceForge as a gzip or bzip2 compressed tar archive.
• Older releases and historical download statistics can also be found on SourceForge.
• The latest code can be downloaded direct from GitHub by clicking the green “Clone or download” button and following the instructions to either clone the git repository or download a ZIP archive.

Installation

There are several ways to install MView:

• Linux, Apple, UNIX
• Windows
• Perl module (advanced)

Testing

Each release of MView is regression tested against hundreds of sample data inputs for all the sequence database search and alignment formats and versions thereof that are supported, together with known edge cases. This is well over 0.5GB of material, so it’s not currently available externally.

Found a bug?

Please open an issue on the MView issue tracker or send an email to biomview@gmail.com.

If MView isn’t able to parse your input file or produces a warning message, it would be very helpful if you can include/attach the data file in your message so that I can (1) quickly reproduce the error, and (2) add the example to the test suite.
