[ESBTL-users] help making a selector (NB)

[Jared T. <tho...@gm...>]

I am just learning ESBTL and am trying to create a line selector that only
returns the HETATMs in the pdb rather than the protein atoms - I wish to
separate the protein and the ligand into two separate systems. Can
someone give me some pointers on how to do this?
