Thank everyone for trying to help me!
I am going to synchrotron.
As Bernie said, I will try to use the closest distance, and 5-10deg.
Thanks again!

Dear All,
I have a small molecule single crystal. I want to solve its structure by x-ray
diffraction.
Could you please teach me how to collect the diffraction data?
I have some experience with protein crystals. But it's the first time for small
molecule.
I don't how to set the parameters, l

Hi All,
Is it possible to define twin operator and twin fraction in the latest version
of Refmac (i.e., in version 5.6.0117) ?
I tried to define these two keywords in Buccaneer but it fails with an error
message "Refmac_5.6.0117: Problem in some of the instructions".
Please help me to fix this.

If your code is already a bit greedy, the scale up is not good.

You need big parallel jobs and avoid sy
Thanks for pointing out that link. The graph makes the point I was going to
mention, i.e. that you notice a big difference in using up to about 4
processors for typical jobs, but after that point the non-parallelisable parts
of the code start to dominate and there's less improvement. This is v
