Individual sequence files can be locked to prevent accidental edits by you or your collaborators.
The bases, annotations, primers, and translations of a locked sequence cannot be edited. Linked analyses and metadata can still be updated.
In order to lock a sequence file, click on the Info icon on the right side panel.
Select Yes next to Locked. Click Update Information.
To unlock a locked sequence file, open the settings and click No next to Locked.
Note: You can also lock projects. Locking a project will lock all of its current sequences and new ones you add. You can still unlock individual sequences in a locked project.
