protassign Command Help
Command: $SCHRODINGER/utilities/protassign
Protein Assignment Script
Usage: protassign [options] <input-MAE> <output-MAE>
Options:
-j Name for the job
-noflip Do not sample ASN/GLN/HIS Chi flips
-nowater Do not sample water orientations
-nopropka Do not use PROPKA for protonation states
-label_pkas Label residues with PROPKA pKas
-asl ASL expression for which residues to sample (default="all")
-noprot_asl ASL expression for which residues to retain input protonation state
-d Print debugging information
-pH pH at which to sample
-propka_pH pH to use with PROPKA ('auto' will attempt to autodect, and use 7.0
otherwise)
-xtal Use crystal symmetry
-include_epik_states
Include Epik embedded ligand states during optimization
-f <res> <state> Force a particular residue to adopt the specified state
Mulitple -f specifications are permitted
<res> is specified as <chain>:<resnum><ins-code>
<state> is one of the following:
For HIS:
HID : delta form
HIE : epsilon form
HIP : protonated form
"Flip HID" : flipped delta form
"Flip HIE" : flipped epsilon form
"Flip HIP" : flipped protonated form
For ASN/GLN:
Flip : flipped form
"No Flip" : unflipped form
For ASP/GLU:
Charged : ionized form
"Neutral 1" : protonated on OE1
"Neutral 2" : protonated on OE2
Example:
protassign -f A:116 HIP -f A:124B "No Flip" input.maegz output.maegz
-minimize Minimize hydrogens of altered species
-seed <int> Seed the random number generator
Job control options:
-HOST <host> - Run job on <host> (Default: localhost)
-LOCAL - Run in the local directory (obsolete)
-NOLOCAL - Run in scratch directory (localhost jobs)
-WAIT - Do not return until the job completes
-NOJOBID - Run the without jobcontrol (previously -NO_REDIRECT)
-h or -help - Print this message and exit
