Hi Reza,
This could be a difference in whether space-group symmetry is being applied in the NCS operators or not. If you do not want it to be applied, use a very large (dummy) cell in your CRYST1 PDB record. (Very recent nightly builds also have the keyword use_space_group_symmetry=False to have the same effect.)
Let me know if that doesn't help!
All the best,
Tom T

Subject: [phenixbb] NCS matrices
Hi,
The translation vector is large, the NCS matrices determined by phenix.simple_ncs_from_pdb do not agree with rotation and translation matrices attained using other software -this does not happen when the translation vectors are small. Is this a bug, or is it from a difference in convention? If the latter, how can one go from the phenix convention to another convention?
Best wishes,
Reza
