Re: [modeller_usage] total of DOPE per residues not equal to global DOPE?

Hi, I have tried to add up all the DOPE score per residue but the value is not equal to the global DOPE score at all. Anyone knows the answer please?

I'm assuming by "DOPE score per residue" that you're making an energy profile with a script similar to the last one shown in the basic tutorial at http://salilab.org/modeller/tutorial/basic.html

The sum over all residues will not generally match the total energy due to two factors - normalization and smoothing. The first (controlled by the normalize_profile argument) "normalizes" the score per residue by dividing the score by the number of restraints on that residue. The second (controlled by smoothing_window) smooths the score per residue by window averaging.

If normalize_profile = False and smoothing_window = 0, the two numbers should be very similar.
