Need a sequence viewer

[hubertofliege]

I need a sequence viewer to do basic alignments of functional genes, but for some reason, MEGA has stopped working. It crashes whenever I try to open files or old sessions. It happens on both my Ubuntu machine and on a Mac my lab has.

I did a google search, but most of these viewers are rather old. Can anyone recommend a reliable sequence viewer?

Thanks.

Artemis - a java-based viewer with ability to search for ORFs and do other simple analyses. Interface is not so great, though.
Unipro Ugene - a real awesome software, including seq viewer, workflow designer and nearly any tool people often use (blast, bunch of alignment tools, etc). Can't be sure, but I think it can even read assemblies.

Artemis is good, but maybe MEGA is more similar to Jalview (can't be sure from your description).

BtW, why do you need a viewer for basic alignments? If they are for further analysis (ie phylogenies, building some sort of models, etc) command-line tools like clustalw or muscle should be ok.

For desktop viewing/simple manual alignment editing you could use Jalview or GeneDoc. If you want to perform more demanding alignments and don't want to use the command line then there are a number of web based multiple sequence alignment tools available for example Clustal Omega or MUSCLE.
