[phenixbb] question about SAD+MR

[Thomas C. Terwilliger]

Hi Qun,
I'm sorry for the problem! That error message means that autosol made a
mistake, not that you are missing something.  I am hoping that perhaps you
are not using a very recent version phenix. Can you possibly try updating
with a recent "nightly build" from the phenix web site and see if that
fixes this problem?  If it does not, please let me know and I will fix it.
All the best,
Tom T
