Did you open the Python code that defines the readcastp command? open read_castp.py Tom

Hi everybody,

I’m following instructions in https://rbvi.github.io/chimerax-recipes/castp/castp.html

open 1pn9 readcastp /Users/george/Downloads/1pn9/1pn9.poc

and get Unknown command: readcastp /Users/george/Downloads/1pn9/1pn9.poc

Any ideas why this is so.

Many thanks
