Maybe it's an NCS 2-fold? A 2-fold rotation matrix is its own inverse/transpose (because you get the same result rotating +180 as -180, which is obviously not true for any other axis order) so the CCP4 & O matrices would be the same for that special case! -- Ian > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of Gerard DVD Kleywegt > Sent: 13 January 2006 09:32 > To: Huiying Li > Cc: CCP4 Bulletin Board; Gerard Kleywegt > Subject: Re: [ccp4bb]: DM and rotation matrix convention > > *** For details on how to be removed from this list visit the *** > *** CCP4 home page http://www.ccp4.ac.uk *** > > > > A related issue is the rotation matrix convention.
