[PyMOL] What is the difference between Atom ID and Index

[Martin H. <ma...@bl...>]

Dear All
I'm trying to figure out for myself, what the two labels 'Label > Atom 
Identifiers > ID' and 'Label > Atom Identifiers > index' mean, or what 
the respective difference between the two is. For sure, the numerical 
value is very different when I show the labels in a structure. ID seems 
to be the index of the atom in the list of atom-descriptor lines in the 
PDB input file. But I cant figure out what 'index' is referring to.

Any help on this would be very welcome.
