Dear Modeller I was using the script Align2D.top below to run modeller with version 6.2. Now that we installed version 7, I just can't get it to work. I get the following message: read_al_375E> Unknown residue type,position,sequence: 1 2 recover____E> ERROR_STATUS >= STOP_ON_ERROR: 1 1 Could you please let me know what is wrong?
