obminimize -- optimize the geometry, minimize the energy for a molecule
obminimize [OPTIONS] filename
The obminimize tool can be used to minimize the energy for molecules inside (multi-)molecule files (e.g., MOL2, etc.)
If no filename is given, obminimize will give all options including the available forcefields.
- -n steps
- Specify the maximum number of steps
- -ff forcefield
- Select the forcefield
View the possible options, including available forcefields:
Minimize the energy for the molecule(s) in file test.mol2:
Minimize the energy for the molecule(s) in file test.mol2 using the Ghemical forcefield:
obminimize -ff Ghemical test.mol2
Minimize the energy for the molecule(s) in file test.mol2 by taking at most 300 geometry optimization steps
obminimize -n 300 test.mol2
