Subject: Phred Quality analysis

[Tony]

Has anyone out there has any sucess storied with long term monetering
of sequence quality using the phred<20 scores for the 3700?
I am currently trying to get a quality system based on phred scores
internally validated and I would like to hear from people who have
done the same thing and how they got on. Amongst my many problems are
assigning cut-offs.

Thankyou in advance
