Hi John,
you didn't specify which language you're using, but in Python you can get it
with
something like this:
=================
import pybel
ob = pybel.ob
import sys
mol = pybel.readfile('mol2', sys.argv[1]).next()
obmol = mol.OBMol
for res in ob.OBResidueIter(obmol):
for atom in ob.OBResidueAtomIter(res):
atName = res.GetAtomID(atom)
print "Atom name:", atName # i.e., CA
=================
Every once in a while this question pops in the mailing list. Does any of the
main
developers think that there would be some use for a dedicated function at the
atom
level?Maybe mapping the same residue function to the OBAtom object?, something
like:
OBAtom::GetAtomID()
