We like Sequencher quite well (we pitched the ABI SeqEd program). The new
version due out early next year is supposed to bring some intelligence to
deleting back 3'and 5'end sequences based on readability of the sequence.
Unfortunately I don't think ABI or GeneCodes is planning on giving us
confidence limits for base calls anytime soon that would allow really good
automatic truncation. In Sequencher the truncated sequence is not deleted
from a project, just suppressed, so it's easy to get back if you need it.
