Dear Modeller users For my research the parameter which i should consider for the best model is from the evaluated program such as PROSA PROCHECK or Verify3D. For Procheck , i use the model which give a quaility of model within >80% core regions. That i used in my project so if any recomments for my research please contact me.
Thank Mr. JItrayut Jitonnom CSML Chiang Mai University Thailand

Hello!
For my protein of interest, I generate 20 models with Modeller, use Modeller's internal objective value to select the five best models, and I evaluate the models with Procheck, Whatif, Vadar, Errat and Prosa2003. I have not yet finalized my selection criteria after evaluation, but I've checked that the selected models are all of satisfactory quality according to these programs. These also help to pinpoint which areas of my multiple alignment might be problematic.

Hello Charlotte!
Thanks for your advice! I'm working with the function value from Modeller. But, I believe that need to refine my models (I'm finding too high values). What are the ranges of values that you find with your models? I'm thinking in refine my alignment.
Thanks, Cassiano Carromeu.
