Version 3.2

NEW:import DNA or protein sequences from EMBL/GenBank/SwissProt
NEW: seaview is now interfaced with the muscle alignment program in addition to clustalw.
NEW: Use "Props:View as proteins" to align protein-coding DNA sequences.
NEW: work with several alignments and copy/paste between them.

SeaView is a graphical multiple sequence alignment editor developped by Manolo Gouy. SeaView is able to read and write various alignment formats (NEXUS, MSF, CLUSTAL, FASTA, PHYLIP, MASE). It allows to manually edit the alignment, and also to run DOT-PLOT or CLUSTALW/MUSCLE programs to locally improve the alignment.

A screen shot of the main window of it is available here.

Use of SeaView

SeaView can be used as a standalone application or as a helper application when using the World Wide Web. In this case, prospective users must configure their WWW browser in a way to make it able to recognize the MIME-type associated to the data read by SeaView: chemical/mase.

Note for MacOS 8-9 users

Seaview needs a fairly recent (1.6) version of CarbonLib to work. See the Apple CarbonLib update page for update instructions.
