positional arguments:
input_file Input file.
output_file Output file. This file will contain structures with
the computed properties.
options:
-h, -help Show this help message and exit.
-minimize Minimize the resulting structures using the requested
force field. The default is not to minimize the
system. (default: False)
-forcefield FORCE_FIELD
Force field to use in energy evaluations. Valid force
fields are OPLS_2005, S-OPLS, SPFF,
MLFF:official:Hybrid_MPNICE,
MLFF:official:Hybrid_MPNICE_I,
MLFF:official:Hybrid_MPNICE_O,
MLFF:official:Inorganic_MPNICE,
MLFF:official:Organic_Crystals_MPNICE and
MLFF:official:Organic_MPNICE (default: OPLS_2005)
-max_structs MAX_STRUCTS
Number of low-energy structures to be saved. (default:
10)
-energy_window ENERGY_WINDOW
Number of low-energy structures to be saved. (default:
None)
-weights ROTATION:TRANSLATION
A colon-delimited list of 2 numbers that defines the
relative frequency of rotations and translations
during Monte Carlo annealing, with the first value
being the weight for rotations.Rotation rotates a
molecule randomly, keeping the center of the molecule
fixed. Translation moves the molecule randomly,
keeping the rotation fixed. A value of 0 for any
weight means that type of move will not be performed.
The default value of 0.5:0.5 indicates that rotation
and translation are equally likely. (default: 0.5:0.5)
-max_rotation DEGREES
The maximum rotation in degrees allowed when
performing a rotation step in the Monte Carlo
annealing. The default is 360.0. (default: 360.0)
-translation_mu MEAN The value of mu in the log-normal distribution that
determines the translation step size. mu gives the
mean value of the distribution. The default mu and
sigma values of 0.25 and 1.00 give maximum probability
to values around 0.5 Angstrom, 40 percent chance of
translations of 1 Angstrom or less, and about a 5
percent chance of translations larger than 7 Angstrom.
(default: 0.25)
-translation_sigma STDDEV
The value of sigma in the log-normal distribution that
determines the translation step size. sigma gives the
standard deviation of the distribution. The default mu
and sigma values of 0.25 and 1.00 give maximum
probability to values around 0.5 Angstrom, 40 percent
chance of translations of 1 Angstrom or less, and
about a 5 percent chance of translations larger than 7
Angstrom. (default: 1.0)
-temperatures TEMP:TEMP:TEMP
A colon-delimited list of temperatures in K that the
Monte Carlo simulated annealing should be run at. The
number of iterations at each step is given by
-iterations. (default: 900:600:300)
-iterations ITERATIONS
The number of Monte Carlo iterations to run during
Monte Carlo annealing. (default: 3000)
-scale_vdw VDW_SCALE_FACTOR
Scale factor for VDW radii to use when computing
clashes. The default is 1.0. (default: 1.0)
-substrate_radius SUBSTRATE_RADIUS
Surface radius to limit Monte Carlo sampling space
around substrate. (default: None)
-finite Treat system as finite. (default: False)
-prepare_desmond Prepare final structures for use in Desmond
simulations. (default: False)
-seed SEED Seed for random number generator. (default: 1234)
-split_components Split system in components when Desmond system is
built. This can speed up the the force field
assignment for systems that contain multiple identical
molecules. (default: False)
Job Control Options:
-HOST <hostname> Run job remotely on the indicated host entry.
(default: localhost)
