 ```Hello John, Unlike the translation parameters, there is no way to directly read what rotation amounts need to be entered. You simply have to try out a few numbers and adjust them until you found a set of rotations that work for the particular image. After a while you tend to get a good feel for the amounts that are necessary for each image. I suggest just playing around with it to observe the effects of different numbers. Keep in mind that the angles are entered in radians, e.g. entering +/-0.2 is equivalent to a rotation of approx. +/-11 degrees. Hope this makes sense, Andreas =================================================== Andreas Finkelmeyer, Ph.D. Institute of Neuroscience, Academic Psychiatry Newcastle University Campus for Ageing and Vitality, Bldg. 15 Westgate Road Newcastle upon Tyne NE4 6BE, UK Tel.: +44 (0)191 256 3296 Fax: +44 (0)191 256 3324 Web: www.ncl.ac.uk/ion >-----Original Message----- >From: SPM (Statistical Parametric Mapping) [mailto:[log in to unmask]] >On Behalf Of John Hope >Sent: 08 August 2011 01:57 >To: [log in to unmask] >Subject: [SPM] Basic question about reorient > >Hi SPM'ers >I am new user of SPM8 I meet a problem of reorient.
