Hi there,
apologies for the previous email, hit the send button too early.
Hope everyone could stand the suspense for the continuation of the story ;-)
Here we go:

I am refining a 1.3AA structure for SSGCID using refmac5.5.102 or 109, OSX.
A typical grey zone case for anisotropic refinement, yet it improves
Rfactors by some 2%. A few B factors go a bit wild though:
"MAKE_U_POSITIVE". Therefore, I try to restrain the sphericity using the
SPHER keyword. Even though the logfile acknowledges the keyword, the
refinements with spher=2 and spher=5 are identical. Is this keyword still
active?

Cheers
Jan
