trajectory_dihedral.py Command Help
Command: $SCHRODINGER/run trajectory_dihedral.py
usage: $SCHRODINGER/run trajectory_dihedral.py -c input_cmsfile
-r residue_numbers (required) -output_csv output_csvfile -chain chain_name
-dihedrals dihedral_types (default backbone) -f frame_frequency (default 1)
Measures 'phi', 'psi', 'omega', 'chi1', 'chi2', 'chi3', 'chi4', 'chi5' for
selected residues over a Desmond trajectory.
Prints out the value of one or more dihedral angles over the course of a
simulation. The residues to monitor can be specified, and the dihedral angle
can be chosen from 'phi', 'psi', 'omega', 'chi1', 'chi2', 'chi3', 'chi4', 'chi5'
'backbone', or 'all'
backbone = Phi and Psi
all = All choices except backbone
For each evaluated frame, a comma-separated list of dihedral values is output to
a specified csv file, one value for each monitored residue.

-v, -version Show the program's version and exit.
-h, -help Show this help message and exit.
-c INPUT_CMSFILE Input cms file.
-chain CHAIN Chain identifier of the input structure corresponding
to the residue numbers. If no chain is specified the
input should haveonly a single chain in it.
-r RESIDUE_NUMBERS Comma-separated residue numbers to monitor. Colons can
be used to specify a range of residue numbers. Any
insertion codes should be specied with individual
residue numbers. If no residue numbers are specified
all residue numbers will be reported. For example:
1,3A,75 or 4A,12:20,172.
-output_csv OUTPUT_CSV
Output csv file. Outputting to CSV will also hide
terminal output
-d {phi,psi,omega,chi1,chi2,chi3,chi4,chi5,backbone,all} [{phi,psi,omega,chi1,chi2,chi3,chi4,chi5,backbone,all} ...], -dihedrals {phi,psi,omega,chi1,chi2,chi3,chi4,chi5,backbone,all} [{phi,psi,omega,chi1,chi2,chi3,chi4,chi5,backbone,all} ...]
Dihedral type to monitor. Must be one or more of the
following: phi, psi, omega, chi1, chi2, chi3, chi4,
chi5, backbone, all. The default is 'backbone'.
-f FREQUENCY, -frequency FREQUENCY
Evaluate frames starting at frame 0, and every Nth
frame after that.
