Description
Options
- -h, --help
-
Print command help and exit.
- -V, --version
-
Print the Force Field X version and exit.
- --wA, --dataWeight=1.0
-
The weight of the experimental data (wA).
X-ray Refinement Options
- -m, --mode=coordinates
-
Refinement mode: coordinates, bfactors and/or occupancies.
- --rmo, --refineMolOcc
-
Refine molecular occupancy.
X-ray Reflection Data Options
- --FSigFCutoff=-1.0
-
F / SigF cutoff (-1.0 is no cutoff).
- --nBins=10
-
The number of refection bins.
- -R, --rFreeFlag=-1
-
R-Free Flag value (-1 attempts to auto-determine from the data).
- -X, --data=<data> <data> <data>
-
Specify input data filename, its weight (wA) and if its from a neutron experiment (e.g. -X filename 1.0 false).
X-ray B-Factor Options
- -B, --bSimWeight=1.0
-
B-Factor similarity weight.
- --nResidueBFactor=0
-
Number of residues per B-factor. 0 uses atomic B-factors (default).
- -U, --addAnisoU
-
Add Anisotropic B-Factors to refinement.
X-ray Target Options
- -A, --allGaussians
-
Use all defined Gaussians for atomic scattering density (the default is to use the top 3).
- --aRadBuffer=0.75
-
Scattering is evaluated within the atomic radius plus this buffer (Å).
- -G, --sampling=0.6
-
The number of grid spaces per Angstrom for the scattering FFT grid.
- --nsf, --noSplineFit
-
Use a resolution dependent spline scale factor.
- --sigmaATol=0.05
-
Sigma A optimization tolerance.
- --xrayScaleTol=1.0e-4
-
X-ray scale optimization tolerance.
X-ray Bulk Solvent Options
- -S, --solventGridSearch
-
Perform a grid search for optimal bulk solvent parameters.
- --sol, --solvent=POLYNOMIAL
-
Bulk solvent scattering model [Polynomial/Gaussian/Binary/None]
