Last week I tried the pdb 7LHY structure where I mutated A:S successfully. When I wanted to try a different mutation I received the error "invalid chain or residue position". I tried different positions and amino acids without any success.
We have now fixed this problem. However, it is currently not possible to mutate the same residue again. You would have to do the mutation from the parent structure, the 'mut_0' structure.
