Yes indeed there is more than one contig builder out there and I agree
completely with Harry that Sequencher is the most powerful. One thing that
caught my attention in the original post was the wording "allows you to
make adjustments". Now if that is meant to mean make adjustments to the
called sequence by comparing to other sequences then yes, the programs
mentioned do this. If it means make adjustments to the raw data data signal
that comes out of a 373A so that one might be able to tweak paramaters so
that more sequence is called, I don't think that program exists. It becomes
evident after using the 373 for awhile that a program that would either
circumvent or enhance the algorithm in ABI's analysis program might be a
useful tool. What do I want this tool to do? 1) Allow me to get inside and
change the base space number if I want. 2) Figure a way to get around the
"all DNA is 25%A25%G25%C25%T" problem. These are _easy_ fixes. Others are
hard. I hear rumours and papers of neural net analysis of this data.
Anybody out there working on something that looks good?
