Thank you Justin.
I tried to define a reference group having the desired orientation and use
-fit. But the box rotates as well. I need to keep the box as it is and just
rotate the solute. Using -fit prompts me to choose the group for least
squares fit and the output, only. When I use -princ in editconf, it orients
the crystal in z direction perfectly. The only problem is that the box
rotates as well, and is not well aligned along the same direction. Any

trjconv -fit with a suitable index group that defines the orientation you
