error in Species delimitation

[liquenologo]

Dear all,
I've been doing some successful tests with a 85 specimens dataset (2
genes, unique haplotypes) using the KC and O'Meara methods for species
delimitation implemented in Brownie. Now I tried to use a larger
dataset of 187 specimens (2 genes, all specimens I have, including
repeated haplotypes) and I repeatedly get the following message:

'Creating initial neighbor-joining tree for samples, based on triplet
overlap. Please be patient.

Now getting distances...
gsl: init_source.c:29: ERROR: matrix dimension n1 must be positive
integer
Default GSL error handler invoked.'

Does anybody know what's the reason for this error and what does it
mean?

Many thanks in advance

Sergio

I'd have to watch what the program is doing to debug it. Please send
me your dataset and I can check it out (probably not until the middle
of next week, though). Thanks for using Brownie!

Best,
Brian

Just to update the list: it appears that there was an error in the
taxa block (it was missing the dimensions and taxlabels statements),
but Brownie should have been giving a more useful error message in
this case. I've modified the code to give a proper error message.

Best,
Brian
