+Modified: Vikram K. Mulligan (vmulligan@flatironinstitute.org) to add support for noncanonicals.
 This mover functions to thread the sequence of a region onto the given pose. Nothing fancy here. Useful when combined with -parser:string_vars option to replace strings within the RosettaScript. For more a more fancy comparative modeling protocol, please see the lovely RosettaCM
 
 ```xml
 <SimpleThreadingMover name="(&string;)" pack_neighbors="(false &bool;)"
         neighbor_dis="(6.0 &real;)" start_position="(&string;)"
         thread_sequence="(&string;)" scorefxn="(&string;)"
-        skip_unknown_mutant="(&bool;)" pack_rounds="(5 &positive_integer;)" />
+        skip_unknown_mutant="(&bool;)" pack_rounds="(5 &positive_integer;)"
+        sequence_mode="(oneletter &SequenceMetric_output_modes;)" />
 ```
 
--   **pack_neighbors**: Option to pack neighbors while threading
--   **neighbor_dis**: Distance to repack neighbor side chains. Repack shell distance for each threaded residue
+-   **pack_neighbors**: Option to pack neighbors while threading.  By default, only the mutated residues, and not the neighbors, are repacked.
+-   **neighbor_dis**: Distance to repack neighbor side chains. Repack shell distance for each threaded residue.  Default 6.0 Angstroms.
 -   **start_position**: (REQUIRED) Position to start thread. PDB numbering (like 30L) or Rosetta pose numbering. PDB numbering parsed at apply time to allow for pose-length changes prior to apply of this mover
--   **thread_sequence**: (REQUIRED) One letter amino acid sequence we will be grafting. Currently only works for canonical amino acids
+-   **thread_sequence**: (REQUIRED) The residue sequence that we will be grafting.  This can be provided as one-letter codes (e.g. "RSTX[DASP]LNE", comma-separated three-letter codes (e.g. "ARG,SER,THR,DAS,LEU,ASN,GLU"), base-names (e.g. "ARG,SER,THR,DASP,LEU,ASN,GLU"), or full names (e.g. "ARG,SER:N_Methylation,THR,DASP,LEU,ASN,GLU"), depending on the setting for sequence_mode.
 -   **scorefxn**: Optional Scorefunction name passed - setup in score function block
--   **skip_unknown_mutant**: Skip unknown amino acid in thread_sequence string instead of throwing an exception
--   **pack_rounds**: Number of packing rounds for threading.  Must be at least 1 so that substitutions are applied.
+-   **skip_unknown_mutant**: Skip unknown amino acids in thread_sequence string instead of throwing an exception.
+-   **pack_rounds**: Number of packing rounds for threading.  Set this to 0 to skip all packing, in which case the new side-chains will likely be in very poor conformations.  Defaults to 5.
+-   **sequence_mode**: The format for the input sequence.  Allowed output formats are: oneletter, threeletter, basename, or fullname.
