If you're only sampling 20 conformers, it's unlikely to be a global minima. It will usually be a lower energy conformer than what you started. Does it need to be further optimized? Well, usually yes, but it depends - the weighted search option does minimize with the MMFF94 force field by default

[Open Babel] Some questions about conformation optimization

2019-09-18 Thread 20520181152664
Thank you for reading this email.I have a question to confirm: I want to get the 3D coordinates of the molecules,after operations just like your example: obabelligand.babel.smi-Oligand.babel.sdf--gen3d--conformer--nconf20--weighted Can we think of this conformation as the most stable conforma
