Tom Hall. North Carolina State University, Department of Microbiology. This is likely to be the final release of BioEdit. There may be some bugs. BioEdit is a mouse-driven, easy-to-use sequence alignment editor and sequence analysis program designed and written by a graduate student. BioEdit can also edit chromatograms, but I find Chromas to be nicer. MEGA also has an alignment editor, but I’ve not really used it very much. Double click on the .

In that case I try and get them close, but each individual one many require adjustment. Indication of selected region on the aligment window not changed. Go View, save options as default.

I select a point in the reverse, then select sequence to the tuhorial Edit, Select to End, control-e. Look in the Desktop or wherever else you saved the edited sequence filesfiles of type All files. Repeat this process for the pstblue1vector. Each group should choose one of the sequence files on the disk, and copy it from drive A to the desktop.

The chromatograms come off the machine with all bases in upper case.

I usually make all of my edits as lower case bases as it makes it easier to identify where I have made edits. You can boedit my bioedit.

Be careful to tutorisl. Enter that information in the header of the MEGA file. Overwrite the sequence title onto the next title shifting up, when the title is being edited. Look in Desktopfiles of type All files. Click on the File menu, Import. Each group should log on to a PC using the class ID bisc and the password pseud.


Not copied to the system clipboard. Select to the end including the current residue.

Sequence editing using BioEdit

Open Bkoedit from the start menu. On the lower toolbar 3rd of the alignment window, select the first solidly colored button.

Tutoriwl the size of the chromatogram trace with the Horizontal scale and Vertical scale bars to the top left of the image. Tutotial on the File menu, Export as text. I manually align them and check for obvious missing bases and either correct them or add a gap to preserve the alignment. This file contains the sequence of the multiple cloning site region of pSTBlue I use BioEdit to align sequences as it is free and has some handy features.

When you first install BioEdit and Chromas, the default will be that BioEdit opens the chromatogram files. Click on the File menu, New alignment. In BioEdit, clean up all the ends and get things to the base pairs you want to analyze. Save the reverse complement as a text file under a different name. Select the N and replace it by typing in the appropriate tutkrial.

Once I am happy with that I ready to create what will become the consensus sequences. Go back to your BioEdit file with all your sequences which should still have the original sequences highlightedpaste the sequences control-sthen delete the selected sequences control-dthus replacing the newly edited ones and removing the originals. I copy the sequence titles to the clipboard Edit, Copy sequence titles. Select tutoriak the reverse sequences and cut them.


I use this feature on nearly every dataset I create. I hate menus, so anything that I can use the keyboard for I tend to change it. BioEdit can also edit chromatograms, but I find Chromas to be nicer. To correct the consensus sequence Tutoeial copy and paste the sequences from a population or individual, group, etc. Select both files with the mouse by dragging it over the file names at the left. Select from the next next residue to the end. Identify the region of vector sequences.

Click on the view menu for the original unedited fileand check Reverse Complement.

Now I select all the forward sequences and cut them and scroll right to check for any bases changes that need to be checked. This highlights any columns that have different bases. Return to your edited forward sequence file, delete the vector sequences, and save for next week. These should show an almost exact match to the forward or reverse sequence.

Also copy the file pstblue1vector. Next go View, Customize Menu Shortcuts.

Make sure your mode is set to edit and insert. Each line in the trace is colour-coded to match the colour that one of the 4 bases is displayed in.
