This command assesses the quality of the model using the GA341
method method [Melo et al., 2002]. The method uses the
percentage sequence identity between the template and the model as a parameter.
MODELLER-produced PDB files contain this information in a 'REMARK'; in the
case of other PDB files, you should supply this by setting model.seq_id.
If the model contains multiple chains, only the first is evaluated by this
method; if you wish to evaluate the model in a different chain, you should
write out that single chain into a new model first. (The method was
parameterized for use with single-chain proteins, so its use for multi-chain
models is not recommended.)
