To quickly obtain the reverse complement of a sequence or part of a sequence, you may select a region on the negative strand and open it in a new view:
right-click a selection on the negative strand | Open selection in New View ()
By doing that, the sequence will be reversed. This is only possible when the double stranded view option is enabled. It is possible to copy the selection and paste it in a word processing program or an e-mail. To obtain a reverse complement of an entire sequence:
Toolbox | Classical Sequence Analysis () | Nucleotide Analysis ()| Reverse Complement Sequence ()
This opens the dialog displayed in figure 17.3:
If a sequence was selected before choosing the Toolbox action, the sequence is now listed in the Selected Elements window of the dialog. Use the arrows to add or remove sequences or sequence lists from the selected elements.
Click Finish to start the tool.
This will open a new view in the View Area displaying the reverse complement of the selected sequence. The new sequence is not saved automatically. To save the sequence, drag it into the Navigation Area or press Ctrl + S ( + S on Mac) to activate a save dialog.
