Dear CCP4 experts, Recently, I was debating a colleague on the pros/cons of refinement done in reciprocal space compared to refinement in real space.
I always thought reciprocal space refinement was preferable since measured amplitudes will be more accurate than calculated phases (unless good experimental phases are available). My colleague argued that with sigmaA and maximum-likelihood methods, calculated phases are much "better" than they were in the past and the two refinement techniques are equivalent in terms of robustness. He said the reason most software hasn't switched entirely to real-space refinement is due to computational issues. Please help enlighten me. All comments/diatribes welcome. Thanks, Mike
