local PDB parser returns empty structure #58

Closed fkaiserbio closed 7 years ago

fkaiserbio commented 7 years ago

if a structure is not found locally, an empty structure is returned
expected: throw an exception

fkaiserbio commented 7 years ago

should be fixed by checking for non-emptyness of parsed atoms
