SYNOPSIS
[OPTIONS ] filenameDESCRIPTION
The obminimize tool can be used to minimize the energy for molecules inside (multi-)molecule files (e.g., MOL2, etc.)OPTIONS
If no filename is given, obminimize will give all options including the available forcefields.- -n steps
- Specify the maximum number of steps (default=2500)
- -cg
- Use conjugate gradients algorithm (default)
- -sd
- Use steepest descent algorithm
- -c criteria
- Set convergence criteria (default=1e-6)
- -ff forcefield
- Select the forcefield
EXAMPLES
View the possible options, including available forcefields:
"obminimize"
Minimize the energy for the molecule(s) in file test.mol2:
"obminimize 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"
Minimize the energy for the molecule(s) in file test.mol2 using the steepest descent algorithm and convergence criteria 1e-5:
"obminimize -sd -c 1e-5 test.mol2"
