NAME

     obminimize — optimize the geometry, minimize the energy for a molecule

SYNOPSIS

     obminimize [OPTIONS] filename

DESCRIPTION

     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
