## [PyMOL] Pymol Symmetry Mates Naming

 [PyMOL] Pymol Symmetry Mates Naming From: - 2009-09-17 23:50:39 ```Hi,all, I am encountering a problem with symmetry mates generated by pymol. It seems that the naming system in pymol and ccp4-supported ACT program are not consistent. I have tested several pdbs in P4212 space group and attempted to figure out the relationship between these two, but failed. I appreciate it if you could hint me out. Some comparisons are listed below. ACT:NSYM ( number of symmetry operation) followed by number of translations of one unit cell along x,y,z. PYMOL: the first two digits are the symmetry operation. The next six digits correspond to the relative integral unit cell translation xxyyzz. I figured that the symmetry operation( the first two digits in pymol) is off by 1 compared to the first digit in ACT, but have no idea how the last six digits relates to the ACT 1em7.pdb pymol ACT 01000000 21-10 02000000 3220 03000000 4010 05000000 6000 05000001 6001 ----------- 1RH4.PDB pymol ACT 000000-1 100-1 03000000 4000 01000000 20-10 ----------- 178l.pdb 01000000 21-10 00000001 1001 030000-1 401-1 070000-1 8110 07000000 8111 03000000 4010 Sincerely Fang Sheng ```
