Hi,
Did anybody actually compare the performance among phenix.refine, CNS
and refmac5? I am trying the phenix.refine from the latest CCI
bundle for my refinement. I have a relative large structure (800 kD
unique) and unit cell (140, 160, 550, 90, 90, 90). The data is at
low resolution ( 3.8 A) with experimental phases. My impression is
that phenix.refine takes a much longer time to finish the jobs, say
rigid body refinement or SA refinement, and it also takes a lot more
memories ( in my case, phenix.refine uses more than 700 MB, but other
programs use less than 200 MB). Is this because the python code in
phenix.refine? CNS and refmac5 are written in FROTRAN, I think. Just
curious.
