Edit a contig

In the Alignment view, you may edit constituent or consensus sequences in an .sqd project contig by removing or adding nucleotides or gaps.

Task	How To
Remove or add gaps	Insert the cursor into an individual sequence and type one or more dashes (-) or delete the same. The consensus sequence will be recalculated to reflect your changes.
Remove or add nucleotides using the keyboard	To remove nucleotides, insert your cursor in the desired location and use the Backspace or Delete keys. To add nucleotides, insert your cursor and begin typing. When you add new nucleotides, they will appear in lower case to signify a manual addition. If you edit one or more constituent sequences, the consensus sequence will be recalculated to reflect your changes. If you add nucleotides to or delete them from the consensus and then restore a trimmed constituent sequence in the same region, the restored sequence will not reflect the insertion/deletion. If you want to ensure that all sequences reflect the changes to the consensus sequence, you should restore trimmed data (see row below) before editing the consensus sequence. Note: If you attempt to add or remove nucleotides using this method, you may receive the following warning: If you still wish to proceed, click OK.
Restore trimmed sequence or trim it even more	Trimmed constituent sequences appear in the view with a small triangle at one or both ends of the sequence. Drag the triangle to either side to reveal previously-trimmed sequence or to trim the sequence even more. If trace data is available for the sequence, you can view this by clicking the plus sign () to the left of the sequence name. Having the trace data displayed can assist you in determining where the trim point should be.
Cut or copy a selected portion of the sequence	Select some or all of the sequence, then right-click and choose Cut or Copy.
Slide a Sanger sequence relative to other sequences	Use the Banana tool (). in the Alignment view header. When this tool is activated, the cursor is shaped like a banana. Use your mouse and the banana-shaped cursor to drag any sequence in the Alignment view to the left or right, as desired. When you are done, click the Banana tool again to return the cursor to its normal state. Note that this tool is only active when the alignment contains Sanger trace files.
Remove a selected sequence from the contig	Select a sequence name at the left of the Alignment view, then choose Sequence > Remove Sequence.

Note that changes made to a constituent sequence only directly affect that sequence, but changes made to the consensus sequence affect the consensus and every constituent sequence in the contig. Note that the original sequence files stored on your computer will not be affected by these procedures.
