Multiple Sequence Alignment and Analysis with Jalview
Channel: Jalview & Dundee Resource Online Training
Date: 2019-11-08

Jalview is a free-to-use sequence alignment and analysis visualisation software linking genomic variants in DNA, protein alignments and 3D structure (http://www.jalview.org/). This video explains how to perform multiple sequence alignment (MSA). It also features the 17 different amino acid conservation measures available in Jalview.

The sequence alignment used in the video can be located at http://www.jalview.org/tutorial/unaligned.fa. 
This exercise can be found in our User Manual, available to download from the Jalview website (http://www.jalview.org/about/documentation). Other Jalview training videos can be viewed in the training section of the website (http://www.jalview.org/training/Training-Videos).

Jalview can access a wide range of databases including PFAM, PDB, EMBL and UniProt. It can read a variety of file formats including FASTA, PFAM, MSF, Clustal, BLC, PIR, Stockholm.
Jalview collaborates with several groups to offer a broad range of sequence analysis tools including: 
• multiple sequence alignment using Clustal Omega, Muscle, MAFFT, ProbCons, T-COFFEES, ClustalW, MSA Prob and GLProb
• tree calculations and principal component analysis (PCA)
• consensus, conservation, and functional site analysis
• secondary structure and disorder predictions
• visualisation of 3D structure.

Jalview (http://www.jalview.org/) has been developed in Geoff Barton's group (https://www.compbio.dundee.ac.uk/) in the School of Life Sciences (https://www.lifesci.dundee.ac.uk/) at the University of Dundee with the funding support of the BBSRC and the Wellcome Trust.
