[gmx-users] Only triclinic boxes

[Rahul Banerjee]

Dear Gromacs users,
		I am getting a strange error when I run mdrun
program for MD. It says,
Warning: Only triclinic boxes with the first vector
parallel to the x-axis and the second vector in the
xy-plane are supported.
 Box (3x3):
 Box[    0]={         nan,          nan,          nan}
 Box[    1]={         nan,          nan,          nan}
 Box[    2]={         nan,          nan,          nan}
         Can not fix pbc.

Afer that program ends due to Segmentation 
Although during Energy Minimisation step this warings
do not occur. Can you please tell me why so happens
and also how to overcome this?

Thanking you in anticipation,

Rahul Banerjee
