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 .

Select the Bioediy and replace it by typing in the appropriate base. BioEdit can also edit chromatograms, but I find Chromas to be nicer. Behavior of BioEdit ver. Before trying to merge the forwards and reverses together, reverse the first reverse sequence Sequence, Nucleic Acid, Reverse Compliment or control-shift-r and align it to your forward sequence usually I have to delete a few bases.
Guide to editing sequences with Chromas and BioEdit
Click on the File menu, Export as text. Close BioEdit, reopen your files and the settings should all be saved. Note that this is also displayed in a 5′-3′ direction, so the sequence complementary to the beginning of your original unedited forward sequence will be at the end of the reverse complement.
If this does not occur, repeat the process with the reverse complement sequence file in a New alignment. Now when you double click on a chromatogram it will open in Chromas. Then I run a NJ analysis to see what is going on with the dataset.
In that case I try and get them close, but each individual one many require adjustment. Select from the next next residue to the end. I copy the sequence titles to the clipboard Edit, Copy sequence titles.

Save the reverse complement as a text file under a different name. The chromatograms come off the machine with all bases in upper case. Change the view type on the lower toolbar 3rd of the alignment windowselect the third colored button from the left says Shade identities and similarities when you hold the mouse over it. Create a new BioEdit file.
I copy all the forwards to a new BioEdit file, select the sequence titles Edit, Select All Sequences, control-shift-a and copy them to clipboard Edit, Copy Sequences, control-amake the new BioEdit file active and paste them in Edit, Paste Sequences, control-s. I select a point in the reverse, then select sequence to the end Edit, Select to End, control-e.
Changing mode from others, the cursor moves one residue before. Indication of selected region on the aligment window not changed. Indication of selected region on the alignment window not changed.
Select from the next residue to the beginning. The most annoying aspect is that you have to manually align up each sequence and manually create a consensus sequence which commercial programs like Tuotrial and Geneious are very good at.
This changes the way the sequences are displayed. I first group all the forwards together, then all the reverses. If the program sticks the. To identify vector sequences, alignments will be prepared between your edited forward and reverse complement sequences and the sequence in the pstblue1vector.
Click on the view menu for the original unedited fileand check Reverse Complement. Note that this works best with coding sequences without indels as every sequence is an identical length, it is all a bit trickier with different length sequences.
Click on Sequence menu, Pairwise alignmentAlign two sequence tutoorial ends to slide. Overwrite the sequence title onto the next title shifting up, when the title is being edited. Next go View, Customize Menu Shortcuts. At that point I finish my consensus sequence.
I always keep the BioEdit file with all forwards, reverses and consensus sequences bioedot that if I double check stuff later it is easier to find the relevant chromatograms I can tell what sequence is from where by the sequence tutorlal.
Highlight the residue to select. Once you set your preferences on one machine you can copy the bioedit. Chromas has the advantage the you can save all of your chromatograms which can subsequently be used in any other programs unlike Sequencher which saves everything in a project file which cannot be opened by anything else.
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. Remove the existing sequences from the first sequence hit biodit, then hit deletethen paste in the ones you just copied.
These are my preferences, you can use these or change them whatever you prefer. Click on StartPrograms, and Bioedit.
Now scroll right again and look for any bases that need checking. To change settings first create a new alignment File, New Alignment or open an existing file.
Sequence editing using BioEdit
One quirk of BioEdit is that if you double click a data file it will open in a new copy of BioEdit, not in an existing one. I usually make all of my edits as lower case bases as it makes it easier to identify where I have made edits.
Drag ruler with the mouse left button on. Then I undo the cut, select all the sequences Edit, Select All Sequences, control-shift-acopy them control-a–note that copy and pasting sequences is different to any other copy and paste action.
