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 use Jalview to edit gaps in a sequence alignment. Jalview's editing interface also allows whole sequences or group of sequences to be moved within an alignment. Editing such as adding or deleting gaps can be done in either the Normal or Cursor mode.

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.
