As for python I would rather use: molecule_chooser_gui("Choose molecule for PISA assembly analysis", lambda imol: pisa_assemblies(imol)) or molecule_chooser_gui("Choose molecule for PISA interface analysis", lambda imol: pisa_interfaces(imol)) The latter has a bug which causes the scripting window to freeze hence the error. Starting the scripting window again solves this issue (not to self: check and fix). So both functions (should) work.

The latter works, but it's not in the menu.

When trying to run PISA from Coot, after choosing the pdf file, I get the following message: “your pisa version is too old. Need at least v1.06”. However, when running CCP4mg (part of the same CCP4 package), I am able to run PISA and get these wonderful interaction surfaces and so on… >> I find all this quite difficult to understand….
