RE:modeller help



Hi Asim,


The  energy scores in modeller are not comparable if you use different sets of
restraints i.e. including/excluing disulfide restraints in your case.

Scores only from the same run i.e. by generating several models, can be
compared.

otherwise the overall energy score is included in the header of the coordinate
file as "REMARK MODELLER OBJECTIVE FUNCTION:  "

Best,

Andras

please take advantage (so others can benefit too) of our modeller user list if
you have other questions.
