[phenixbb] [ccp4bb] Phenix; converting a map to structure factors

[Smith Liu]

Dear Terwilliger,
 
Is any software convert mtz file into mrc file (for viewing in chimera)?
 
In addition, by mrc file I can run phenix,real_space_refine very nicely. But for knowledge gaining purpose, I convert a mrc file to a mtz file by phenix.map_to_structure_factors, and then run the GUI phenix refine with the phenix.map_to_structure_factors converted mtz file (from mrc) file and a model PDB (from mrc), first the GUI phenix refine will give very high Rwork and Rfree, secondly the mtz output density by GUI phenix looks does not fit the initial mrc density at all, thus the pdb models given by phenix,real_space_refine and GUI phenix refine seem strongly different.
 
Is any way to get similar pdb models by phenix,real_space_refine and GUI phenix refine?
 
Best regards.
 
Smith

Hi Reza,


Just use:


    phenix.map_to_structure_factors map.ccp4 d_min=2.5


or something like that,
All the best,
