Hi Eleanor,
C2 - this was XDS lingo or Bravais talk :-)

I don't really understand what your space group is? space group mC???

Hi all,
I was trying to solve the structure of a protein in several different datasets
using xds and phenix. I could solve the structure from one dataset in space
group P4. For another dataset, I could solve the structure using the monomer of
the structure I got from the first dataset as search model and solve the
structure in space group mC. For the third dataset, in IDXREF.LP, the space
group of the highest symmetry is hp: 101.2, 101.3, 58.8, 90, 90, 120. According
to Mathiews coefficient, 1 monomer is expected in the asymmetric unit. But I
couldn't get the molecular replacement solution using the same method as for
the second dataset. I also tried several other search models (eg. deletion of
the potential flexible region in the search model) and tried to find the
solution in all possible pointgroup. I also tried to process the data in oC
(C222), the space group of the second highest symmetry in IDXREF.LP, but, still
I could not get right molecular replacement solution. I don't whether this
means that there is a big conformational change for the structure in the third
dataset or the space group I use is not right. Let me know if any of you would
have any comments or suggestions for me. Thank you so much!
Best,
Wei
