[phenixbb] Molecular replacement at low resolution

Dear developers

I have a dataset to about 4 A in point group P 4 2 2 (Pointless suggests P
41 21 2). The protein is about 11 kDa and has an identity of about 50 % to
my search model. Phaser calculated the eLLG to be about 5, and maybe not
surprisingly, it failed even after using Sculptor to prepare the model.

It also says that solutions with Z-scores more than 8 were rejected for
failing the packing test. Are there any suggestions on getting a solution?

Solvent content calculation from Xtriage suggests about 8 copies in the
asu. Would this be of any help in MR?

Thanks.
