Hi everyone,
I would like to use surface_docking on a pdb containing carbohydrates.
I put as residue name “Glc” in my pdb and I added the flag:extra_res_fa=/media/storage/a/software/rosetta_src_2015.02.57538_bundle/main/database/chemical/residue_type_sets/fa_standard/residue_types/carbohydrates/to4-beta-D-Glcp.params
However I get the following error:
ERROR: No match found for unrecognized residue at position 1
Looking for lower-terminal residue with 3-letter code: Glc
ERROR:: Exit from: src/core/io/pdb/file_data.cc line: 1216Does someone know how to fix the problem?
Thanks,
Camille -

To enable carbohydrate functionality in Rosetta, one has to use the
-include_sugars
flag. Do not use the-extra_res_fa
flag.In addition, the
.pdb
file must includeHETNAM
records.An example
HETNAM
record looks like this:HETNAM Glc X 1 ->4)-beta-D-Glcp
…where
Glc
is the 3-letter code,X
is the chain id,1
is the residue number, and->4)-beta-D-Glcp
is the uniqueResidueType
name.That being said, understand that carbohydrates are not fully implemented yet. It’s a work in progress and nothing is fully calibrated and little is published yet. If you need more assistance or would like to collaborate, please contact me at

Unfortunately I put both in my pdb but rosetta gives the same error. Do you have another idea to make it work ?
Thanks for your help. -

Thank you for your answer.
I have some troubles concerning the way to write HETNAM records.
For example two blocks :
HETATM 1 C1 Glc B 1 0.148 -0.342 0.449 1.00 0.00 M0 C
HETATM 2 C2 Glc B 1 -0.032 -1.499 -0.536 1.00 0.00 M0 C

HETNAM Glc B 1 ->4)-beta-D-Glcp
HETNAM Glc B 2 ->4)-beta-D-Glcp
?How can I define the coordinates then?
Thanks,

The HETNAM records are different from the HETATM record.
HETNAM records are additional records found in the “header” portion of the PDB (http://www.wwpdb.org/documentation/file-format-content/format33/sect4.html#HETNAM) and provide chemical name information for the heterogens in the PDB.
HETATM records are records found in the coordinates portion of the PDB (http://www.wwpdb.org/documentation/file-format-content/format33/sect9.html#HETATM) and provide the coordinates for the heterogens.
Your PDB should have both.

It may be best to post your edited PDB here, so we can check formatting and the like.
