SSEdit is a MacOS X application for viewing and editing single sequences. Input and output files in FASTA, NRBF, Staden and other formats are supported with the capability to recognise some by the file extension name.
Avogadro is an advanced molecule editor and visualizer designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas. It offers flexible high quality rendering and a powerful plugin architecture.
ApE (A Plasmid Editor) is an integrated program for plasmid construction and visualization. It includes a sequence editor, a linear text map identifying sequence features such as restriction sites and ORFs, and a graphic view that highlights sites and features in your sequences. A program designed by a molecular biologist, for molecular biologists.
Apollo is the first instantaneous, collaborative genomic annotation editor available on the Web.
Web Apollo is designed to support geographically dispersed researchers, and the work of a distributed community is coordinated through automatic synchronization: all edits in one client are instantly pushed to all other clients, allowing users to see annotation updates from collaborators in real-time during the editing process.
Baobab is an editor for large phylogenetic trees written in Java. It allows you to create and/or modify a tree interactively, adding/(re)moving branches and nodes, changing leave names, setting parameters. Baobab focuses on edition, not representation and display that are only used as a tool to make edition easier.
Jalview is a system for interactive WYSIWYG editing, analysis and annotation of multiple sequence alignments. Core features include keyboard and mouse-based editing, multiple views and alignment overviews, and linked structure display with Jmol. Jalview is available in two forms: a lightweight Java applet for use in web applications, and a powerful desktop application that employs web services for sequence alignment, secondary structure prediction and the retrieval of alignments, sequences, annotation and structures from public databases and any DAS 1.53 compliant sequence or annotation server.
