Upon executing the MAKE_RESTRAINTS command, the following is displayed:

>> ENERGY; Differences between the model's features and restraints: preppdf_449W> No atoms selected; no restraints will be selected. preppdf_450E> Probably because no MODEL is in memory; use READ_MODEL. recover____E> ERROR_STATUS >= STOP_ON_ERROR: 1 1

Upon executing the READ_MODEL command, I receive the following:

iatmcls_286W> MODEL atom not classified: LEU:OT1 LEU

Please give your suggestions. Thanking you,
