[BiO BB] MrBayes - Memory overflow

[Jose Maria Gonzalez Izarzugaza]

Hello everyone.

Does anybody know how i could limit the memory usage while creating a 
consensus tree with MrBayes? (even though i am using a 2GB RAM computer)

The problem (segmentation fault) only appears when i'm trying to build a 
tree with more than 40 taxa, so the problem is not in the compilation, 
nor in the commands given.

my mrbayes command is:
sumt filename=filewithALLtrees contype=allcompat burnin=1500

Many thanks in advance.

Regards,
Txema
