[gmx-users] drawing chemicals 2d sketchs

[Alan]

Hi List,

OK, it may be a bit off-topic, but I am looking for a software to,
given a pdb of a small molecule, draw a 2d chemical structure, but:

- if possible free
- if possible for Mac Osx, then Linux (perhaps Windows)
- able to show labels numbers and atom type.

If someone knows a program with that features I would appreciate very
much your help.

Many thanks in advance.
Alan
