I use BioEdit to align sequences as it is free and has some handy features. It is the only program I know of that allows you to edit, search and replace, and paste over the sequence title names independent of your sequences. BioEdit lets you modify just about anything that it does relative to menus and keyboard short cuts as well as the default settings for displaying data. Select to the end including the current residue.Ĭlick on the edited forward sequence file to open it.
Then I run a NJ analysis to see what is going on with the dataset. Select them tuutorial control-acopy to clipboard control-cgo back to BioEdit, to paste these names over the existing ones.

Eventually the forwards will start to be a poor match to the tutoria. I check any unique differences by opening the chromatogram. If the vector sequence is on the same strand as the forward sequence, the vector should have a region of exact or almost exact homology with the beginning of the forward sequence. To correct the consensus sequence I copy and paste the sequences from a population or individual, group, etc.Įnter that information in the header of the MEGA file. ĭepending on how well your reverse sequences overlap with your forwards, scroll right until they overlap with good sequences. MEGA also has an alignment editor, but I’ve not really used it very much. BioEdit can also edit chromatograms, but I find Chromas to be nicer. BioEdit is a mouse-driven, easy-to-use sequence alignment editor and sequence analysis program designed and written by a graduate student. This is likely to be the final release of BioEdit.
