Dear all,
 
I'm trying to model a protein structure using two homologous proteins as templates. I wonder how much the two known structures should be close for the modeling because I get errors like the following,
 
stdevs__397E> STDEV < 0:       -0.3487
              Set to 1E-5.
 
When I used the two known structures separately one by one, the modeling worked fine.
 
Cheers,
Han
