When trying to read a pdb file that does not exist on my disk I get a puzzling message :

mh = IMP.atom.read_pdb(pdbFilePath,m,sel)

NotImplementedError: Wrong number of arguments for overloaded function 'read_pdb'.

Possible C/C++ prototypes are:

IMP::atom::read_pdb(IMP::TextInput,IMP::Model *)

IMP::atom::read_pdb(IMP::TextInput,IMP::Model *,IMP::atom::PDBSelector const &,bool)

IMP::atom::read_pdb(IMP::TextInput,IMP::Model *,IMP::atom::PDBSelector const &)
