Hi, Does the input file contain 3D-coordinates? As far as I have seen, neither confab nor conformer will generate an initial 3D structure if it’s not already present. Kind regards, Fredrik 6 maj 2014 kl. 19:39 skrev Douglas Houston dhous...@staffmail.ed.ac.uk: Anyone have any comment on

[Open Babel] Creating an OBMol by hand in C++

2014-05-07 Thread Nicolas Cheron
Dear all, I am working with a program (in C++) which has its own way of dealing with atoms and molecules. I would like to use the OpenBabel library to assign types to atoms. For now, when I need to do it I write a .xyz file and then read it in an OBMol object and assign the types. This works,
