Hi Pavel, Yes, I am using torsion angle NCS in phenix.refine. I don't mean the NCS matrices, but the torsion NCS details. Here's an example of the REMARK 3 NCS that Phenix 1.8.2-1309 used to write in the PDB header and that have disappeared from the PDB header with Phenix 1.8.3-1479 and 1.8.4-1496: REMARK 3 TORSION NCS DETAILS. REMARK 3 NUMBER OF NCS GROUPS : 1 REMARK 3 NCS GROUP : 1 REMARK 3 SELECTION : chain 'A' REMARK 3 SELECTION : chain 'B' REMARK 3 RESTRAINED TORSIONS: 4042 REMARK 3 BELOW LIMIT RMSD : 0.620 REMARK 3 ALL RESTRAINT RMSD : 4.081 REMARK 3 Histogram of differences under limit: REMARK 3 0.000 - 1.500: 3932 REMARK 3 1.500 - 3.000: 87 REMARK 3 3.000 - 4.500: 5 REMARK 3 4.500 - 6.000: 4 REMARK 3 6.000 - 7.500: 1 REMARK 3 7.500 - 9.000: 0 REMARK 3 9.000 - 10.500: 0 REMARK 3 10.500 - 12.000: 0 REMARK 3 12.000 - 13.500: 1 REMARK 3 13.500 - 15.000: 0 REMARK 3 Histogram of differences over limit: REMARK 3 15.000 - 22.400: 0 REMARK 3 22.400 - 29.800: 0 REMARK 3 29.800 - 37.200: 0 REMARK 3 37.200 - 44.600: 0 REMARK 3 44.600 - 52.000: 1 REMARK 3 52.000 - 59.400: 3 REMARK 3 59.400 - 66.800: 0 REMARK 3 66.800 - 74.200: 0 REMARK 3 74.200 - 81.600: 4 REMARK 3 81.600 - 89.000: 4 Luca On 3 Oct 2013, at 00:39, Pavel Afonine wrote:
Hi Luca,
when NCS is enabled phenix.refine uses torsion angle NCS by default.. This may explain why you don't get NCS matrices in your PDB file. Is that the case?

Hello,
I have noticed that Phenix 1.8.4-1496 (as well as 1.8.3-1479) appears to have stopped writing the REMARK 3 NCS in the PDB header. Is this so? It is useful to have that info when it comes to depositing the coordinates.
Many thanks, Luca
