Hi Francis, No, I don't think it is the same as OMAT format.Here is the format from phenix.simple_ncs_from_pdb (identical to the format from resolve): (Mapping molecule j onto molecule 1) (As input) Operator # 1 New X-prime= 1.0000 X + 0.0000 Y + 0.0000 Z + 0.0000 New Y-prime= 0.0000 X + 1.0000 Y + 0.0000 Z + 0.0000 New Z-prime= 0.0000 X + 0.0000 Y + 1.0000 Z + 0.0000 Approximate center_of_mass of this object (from center_of_mass of object 1 and NC symmetry) is -28.39 18.81 -16.36 Operator # 2 New X-prime= -1.0000 X + -0.0035 Y + -0.0040 Z + -4.1335 New Y-prime= 0.0043 X + -0.1070 Y + -0.9943 Z +-21.6192 New Z-prime= 0.0031 X + -0.9943 Y + 0.1070 Z +-19.2559 Approximate center_of_mass of this object (from center_of_mass of object 1 and NC symmetry) is 24.44 -7.12 -39.79 would be represnted as: rota_matrix 1.0000 0.0000 0.0000 rota_matrix 0.0000 1.0000 0.0000 rota_matrix 0.0000 0.0000 1.0000 tran_orth 0.0000 0.0000 0.0000 center_orth -28.3915 18.8125 -16.3621 rota_matrix -1.0000 -0.0035 -0.0040 rota_matrix 0.0043 -0.1070 -0.9943 rota_matrix 0.0031 -0.9943 0.1070 tran_orth -4.1335 -21.6192 -19.2559 center_orth 24.4419 -7.1171 -39.7930 This is in contrast to OMAT: O/RAVE Format OMAT r11 r21 r31 (note that the rotation matrix is r12 r22 r32 transposed with respect to CCP4 r13 r23 r33 or conventional matrix format) t1 t2 t3 where x' = r11 x + r12 y + r13 z + t1 y' = r21 x + r22 y + r23 z + t2 z' = r31 x + r32 y + r33 z + t3 I hope that helps! -Tom T
Is the output rota_matrix (x3), and tran_orth(x1) in OMAT format?
Thanks
F
