?Hi Ashok,

If you have a PDB file with 2 crystallographically-related copies of your molecule, with one called chain A and one called chain B, you can run phenix.simple_ncs_from_pdb on your PDB file to find the matrices and translations.  Let me know if that doesn't do it!

All the best,

Tom T

Hello Phenix BB,
Like every amateur crystallographer I could easily generate symmetry mates in a given radius in coot, but I wondered always which is the crystallographic two fold axis axis(my space group being C2) through which the molecule is rotated and translated (if it is) to get the next molecule. I tried superpose to find the answer, but could only get the Euler angles and transformation matrix and not the axis. Are there any programs where I can get to know this, would be grateful to be enlightened for the same

thanks BB in advance
