Hi, I'd really like to use Modrefiner or FG-MD to be able to generate structural models for a protein with a non-natural amino acid (i.e. not one of the standard 20 amino acids) inserted into it, given that we have an accurate model of the WT protein. I know from crystallography that it is common to be able to make a topology for the new amino acid file that then can be read into the refinement software so that it can accurately refine the unnatural amino acid along with the natural amino acids- is anything like that possible with either modrefiner or FG-MD?
Thanks,
Scott
