Dear Modeller,
 
My top file contains user-defined restraints involving hydrogen atoms.
 
When I add 'SET DO_LOOPS =1' to the top file, the modeller has the following error.
 
add_res_442E> One or more atoms absent from MODEL:  O:381: HD1:381:
 
I guess this is related to that LOOPS optimizes nonhydrogen  atoms. Is there a way around this problem?
 
Best regards,
Han
