Dear All,

Happy New Year

I am working with a 2.06 Ang resolution structure in F432 space group and
further using REFMAC (also tried Phenix) program for refinement of my
model.

Every thing in the structure seems good, R factor/ R free= 18.59/20.77 but
the structure is too noisy (blobs of difference Fourier with red as well as
green density).

As such electron density is looking good for the protein part.

Is there any parameter which i had to check.

Thanking you in advance

Rajan
