Yes, this is along the line of what I had in mind.
Two data sets, one 'messy' and one 'clean'.
The problem here is the extent of 'messiness',
we want to able to complete the search. I have a set of
sequences, but PAUP runs out of memory @18,000 trees.
I have a 'clean' data set, but this is only due to a lack of
What I would like to do is post both data sets to the newsgroup (see below),
hopefully some people will run them for us, and I can gather a list of
(is PAUP* 4.0 quicker on IBM or MAC, what about Mainframe UNIX machines),
'clock speed' , operating system (e.g. Mac OS 7.5.5 -vs- Mac OS 8.5, etc..),
and how fast the search was completed.
We should also do this for other searches in PAUP such a ml, etc. and for
Posting data sets.- I know some newsgroups are not very keen on 'binaries'
mainly due to problems people have downloading data from their ISPs (i.e.
they are on the phone longer),
but this group I guess is mainly academic and we don't have to pay for our
The alternative is to get in contact with me directly, and I we can go from
there in devising some
sort of strategy.
