Hi Maia, the R-factors seem good at this resolution. If the other validation criteria, local and global, are ok, then I wouldn't worry too much about this error anyway, since its estimation is not always reliable. For example, as local validation use phenix.real_space_correlation to plot map CC for each atom - this will give you the ideal local fit of your model into electron density map. Use Molprobity for geoemtry validations, etc. Cheers, Pavel. On 3/14/09 12:24 PM, Maia Cherney wrote:
Hi all, I am wondering why I am getting a large coordinate error of 2.17A in the phenix refinement of the structure that I earlier refined in CNS (2.4A resolution). Is it normal or why is it happening? How to fix it? Rwork and Rfree are 18% and 22%.
