Instead of using a different tool for each step and then having to constantly export and import data in varying formats, you can do everything from automated alignment to exporting the final likelihood tree as a vector graphic in one comprehensive program. One of its strengths is that it is to a large degree a GUI that combines and greatly facilitates the use of established freeware programs provided by other scientists, such as the alignment and phylogenetics modules mentioned above. Lastly, SeaView has some purely technical advantages over other sequence alignment editors I have used: It is a small, easily installed and fast package, so far it seems very stable, and it is available for all major operating systems. (Just about the only thing that annoyingly cannot be changed is how many letters of the sample name are displayed, so don't make them too long.) You can set anything from the colours the various bases are displayed in to the font size used for the alignment. in Inkscape.Īs for the design, the display of sequence data looks a bit garishly colourful at first but it is endlessly customizable. When you have inferred a phylogenetic tree, SeaView opens it in a separate window where you can reroot it, display it as circle tree, cladogram or phylogram, display support values or branch lengths, and finally export it in Newick format or as SVG or PS vector graphics for further editing e.g. For publication I generally want all the most parsimonious trees so I will continue to use TNT or PAUP instead, but for likelihood analyses or simply for quick and dirty data exploration before the real analysis SeaView is definitely an option. The disadvantage of the parsimony module is that it appears to return only the consensus tree. Branch support can be inferred with bootstrapping and, in the case of likelihood, the aLRT test. Likelihood analyses can be run with seven different substitution models. The analyses are quite fast and allow all the major settings one would expect, although they do not include TBR branch swapping. I have so far tried parsimony, which uses a PHYLIP module, and likelihood, which uses the PhyML software. But the best thing is, you do not necessarily have to do that because SeaView itself provides modules to immediately conduct parsimony, distance and likelihood analyses. If you want to move your finished alignments into a phylogenetics tool, it can be saved in a variety of formats, the most important probably fasta, nexus (for PAUP, MrBayes, BEAST) and phylip (for RAxML or, obviously, PHYLIP). Strangely, however, it ignores all sites that have gaps even in only one sequence, so it is not suitable for obtaining the relevant statistics for publication. This would have made some previous projects a bit easier.Īnother helpful function is Props -> Statistics because it quickly gives an overview of variability in the dataset, how many sites are parsimony informative and suchlike. The only disadvantage is that it does not fill the missing sequences in each block with Ns but merely with gaps, but at least this function makes concatenation much easier than with a text editor.

Simply open the datasets in different windows of SeaView and use File -> Concatenate. If sample names are identical between datasets (and if they aren't, it's your fault), it is easy to concatenate them. It has two automated alignment options, the venerable ClustalW and Muscle, the latter one in my experience the better of the two. In all other areas SeaView appears to have the advantage, at least at first sight. Where SeaView gives us only the option of typing and deleting individual bases or indels, BioEdit has a drag-and-drop and a grab-and-drag function, both with useful extra settings such as whether only the marked area should be moved or whether the bases to the right should move as a block.

The one I found, SeaView, may in some regards be even better.Īdmittedly, BioEdit has more options for manual sequence editing. When installing programs on Linux, I sought for an open source alternative to the sequence alignment editor BioEdit that I have been using on Windows since I was an undergrad.

EXPORTING CLUSTALW SEQUENCES FROM BIOEDIT SOFTWARE
As mentioned in my last post, I have recently stumbled across a really great and handy software tool for molecular phylogenetics.
