[phenixbb] AssertionError & TLS

[Kanchan Anand]

Hello everybody,

I am a new user of Phenix and presently trying to refine 3.6 A data of a 
protein-RNA complex.
whenever i add tls into my .def file for the next run, i get this problem:

Traceback (most recent call last):
 File "/data/software/phenix-1.3b/phenix/phenix/command_line/refine.py",

in split _u
   assert (u_iso < 0.0).count(True) == 0

I have downloaded the new 1.3b version and without tls the program runs 
fine!

could you please help

Thanks in advance
