Hello all- I have been trying to use autobuild with a semet dataset. I have checked the "build semet residues" option in the autobuild gui. At some point after the composite build, the error below is generated and the final model has been stripped of all semethionines. I am using phenix version 1.8.4-1496 on a macbook. I have now downloaded the new version. But can someone expand on my problem. My input sequence and model pdb contain Methionine but I expected the rebuild process to alter them. Should I change the one letter code for semet from m to something else. -Todd . . . .
