[phenixbb] RunTime_errors

[Xue-Yuan Pei]

Dear phenix experts:
I have a data in R32 at 2.3A. 4 molecules/A.U. I got the following 
error message when I run refinement wiht phenix v1.5-2:

=============================== refinement start 
==============================

Traceback (most recent call last):

is too big
  maximum allowed size is 67108863 64 bit OS and software might be required 
for such a big mask.



How can I tackle this problem? Any suggestion is highly appreciated.
