Manual trimming
Sequence reads can be trimmed manually while inspecting their trace
and quality data. Trimming sequences manually corresponds to adding
annotation (see also Adding and modifying
annotations) but is special in the
sense that trimming can only be applied to the ends of a sequence:
double-click the sequence to trim in the Navigation Area | select the region you want to trim | right-click the selection | Trim sequence left/right to determine the direction of the trimming
This will add a trimming annotation to the end of the sequence in the selected direction. Note that no sequence is being deleted, in stead the trim annotation signals that the sequence is to be ignored during further analyses).
