Hi Juan,
FYI - you forgot to reply to the mailing list in your previous email...
As for the problem, as Eric mentioned, it seems to be a problem with your
plot_posterior_nodes function. That one is out of the matplotlib library,
and I guess it belongs to the HDDM package. You might want to ask people in
their mailing list for more help,
Shawn
