Hi Modellers,
I have a question regarding the objective function in the output
file(.B99....) of MODELLER.
I've been evaluating the models that run by MODELLER. I selected three
best models from my running results based on their objective function( the
lower the better). Each objective function of them is like following:
A: 6103.3325,
B: 6090.5195,
C: 6077.6436.
Then I used ProsaII to calulate the z- scores after I did CHARRM energy
minimization. The zp-comb of them are
A: -5.69,
B: -3.82,
C: -5.87.
>From Modeller I can see B and C might have better models than A does. But
from ProsaII, I can exclude B. Does this kind of thing happen before? I'd
like to know if I should include as many as models I have to run Prosa, in
case the models with higher objective functions have lower z-scores.
Thank you very much.
Sincerely,
Violet
