[phenixbb] what about heavy atom as model for MR

[赵岩]

Hi everyone,

The heavy atoms(Se-Met) were located at P4322 space group(4A). But the initial
density map is so bad that I can not build the initial model. 

Meanwhile, I have another two datasets, native(2.6A) and  se-met anomalous
dataset with space group P2221. But these two datasets have no solution. I have
tried the initial map from sp P4322 as a model to do molecular  replacement.
But no MR solution. 

So, I want to know how can I use the heavy atom as model to do MR with
isomorphous or anomalous differences?

Thanks!
