I am using RNA structures generated by the MC-Sym|MC-Fold algorithm and docking it with ER-alpha receptor protein(PDB ID:1SJ0).
I am getting the following error:
There was an inconsistency in your data
Second pdb file contains an unknown amino acid or nucleic acid base C
Make sure to use three letter code for bases and amino acid
Can anybody inform me as to what is wrong? Thank you.
