Re: CCL:charges and database, multimol2 file



Hi Carsten,
 MDL's Cheshire scripting language is a possiblity.  It ships with various SDfile
 scanning utilities, and a PEOE (sigma only) partial charge calculator based on
 Gasteiger's work is one of the example scripts.  Implicit hydrogens are
 trivially obtainable except for transition metals where the valence evaluation
 becomes problematic.
