Does antibody_numbering_converter support camelid antibody?

Hi all,

      We downloaded Complex of a camelid single-domain vhh antibody 2P43, used Discovery Studio to change  the numbering scheme of the PDB file to  Chothia, then when we want to used "antibody_numbering_converter" to  change the numbering scheme of the PDB file from Chothia to AHo, an error occurred,  the command we used is " antibody_numbering_converter.linuxgccrelease -s 2P43_clo.pdb -camelid true -input_ab_scheme Chothia -output_ab_scheme AHo ",  the error is as follow:

ERROR: AntibodyNumberingConverterMover only works with L and H chains. 
ERROR:: Exit from: src/protocols/antibody/AntibodyNumberingConverterMover.cc line: 140

Does  antibody_numbering_converter  support  camelid antibody?
