Hi Almudena, the error message tries to tell you that for (0, 0, 16) index corresponding R-free-flag(+) and R-free-flag(-) are different indicating that something must have gone wrong when you were manipulating the files or may be the original tool that you used to create R-free-flag did it incorrectly. Can you send me that MTZ file and also explain how you obtained it? Pavel On 3/20/15 7:06 AM, Almudena Ponce Salvatierra wrote:
Hi everyone,
I have merged 3 mtz files into one and done successfully Molecular replacement with it. However when I try to refine, I get the following error message: "cctbx error: merge_equivalents_exact: imcompatible flags for hkl (0, 0, 16) (mismatch between Friedel pairs).
How can I fix this?
Thank you very much in advance.
Best,
Almudena
