Jalview is a desktop application for interactive analysis, visualization, and editing of multiple sequence alignments that integrates sequence annotation, secondary structure, and phylogenetic trees. It provides a graphical environment used in conjunction with databases and tools from the life sciences community, including resources developed at European Bioinformatics Institute, National Center for Biotechnology Information, Protein Data Bank, UniProt, and collaborative projects associated with Wellcome Trust and Biotechnology and Biological Sciences Research Council. Jalview is widely adopted in academic laboratories, teaching environments, and computational biology platforms such as Galaxy (platform), Ensembl, and UCSC Genome Browser.

Introduction

Jalview was created to bridge interactive visualization with programmatic analysis, connecting sequence alignment editors to structural viewers, annotation databases, and phylogenetic inference programs. The project interlinks with toolchains and institutions including Clustal, MAFFT, MUSCLE (bioinformatics), Phylip, and RAxML to provide workflows that span the needs of molecular biologists, structural biologists, and bioinformaticians. It has been used alongside software and resources from EMBL-EBI, Swiss Institute of Bioinformatics, European Molecular Biology Laboratory, and consortia like ELIXIR.

Features and Functionality

Jalview supports interactive multiple sequence alignment visualization, coloring schemes, annotation tracks, and consensus displays that integrate data from UniProtKB, PROSITE, Pfam, InterPro, and Gene Ontology. The application includes secondary structure visualization linked to annotations from Protein Data Bank, DSSP (database), and structural alignment tools used in studies involving X-ray crystallography, Nuclear magnetic resonance spectroscopy, and Cryo-electron microscopy. Jalview's tree-building interfaces call external programs such as Clustal Omega, FastTree, and PhyML (software), and it supports export formats compatible with Newick format, SVG, and PDF for use in publications and presentations at venues like Gordon Research Conferences and Cold Spring Harbor Laboratory courses.

Architecture and Implementation

Implemented primarily in Java (programming language), Jalview uses a modular architecture that integrates GUI components, parsers, and plug-in-like connectors to web services hosted by EBI, NCBI, and other providers. The architecture enables linking to web services using protocols exemplified by REST (computing), SOAP, and BioMoby, and integrates with workflow engines such as Taverna, Snakemake, and Nextflow. The software interoperates with file formats established by European Molecular Biology Laboratory-European Bioinformatics Institute and the International Nucleotide Sequence Database Collaboration, including FASTA, CLUSTAL format, and Stockholm format.

Usage and Applications

Jalview is applied in sequence curation projects at institutions like UniProt Consortium and in educational settings at University of Dundee, University of Oxford, and University of Cambridge, where instructors demonstrate alignment editing alongside resources from EMBL, European Bioinformatics Institute, and the Wellcome Sanger Institute. Researchers use it to annotate conserved motifs from PROSITE, map domains from Pfam to alignments used in studies of proteins deposited in the Protein Data Bank, and to visualize evolutionary relationships inferred with tools from TreeBASE and Phylogenetics-focused laboratories. It also features in pipelines that combine structural modeling packages like MODELLER and visualization with PyMOL or UCSF Chimera for integrative studies presented at conferences such as ISMB and workshops organized by ELIXIR.

Development and Release History

Development originated in the early 2000s at research groups associated with University of Dundee and collaborators at European Bioinformatics Institute and has evolved through community contributions involving developers tied to Wellcome Trust-funded projects and initiatives from the Biotechnology and Biological Sciences Research Council. Releases have tracked changes in the Java Platform ecosystem and periodic integration with alignment algorithms from groups responsible for MAFFT, MUSCLE (bioinformatics), and Clustal Omega. Development milestones have been highlighted in peer-reviewed venues such as articles in Bioinformatics (journal), presentations at ISMB, and technical reports circulated among members of the Global Alliance for Genomics and Health.

Licensing and Distribution

Jalview is distributed under an open-source license chosen to facilitate academic and commercial use, aligning with distribution channels employed by projects from Open Source Initiative-aligned repositories and package managers common in the Bioinformatics community. Binary and source distributions have been made available through institutional mirrors and community platforms used by collaborators including European Bioinformatics Institute, GitHub, and university-hosted archives, enabling integration with computational environments managed by teams at Wellcome Sanger Institute, EMBL-EBI, and other research centers.
