Dear John,
I am coming back to this issue as I am not sure I understand how to deal with it. I get this warning when displaying with "Display" DICOM-converted images (T1-weighted volumes, using the SPM tool -scanner was a General Electric SIGNA HDx 3.0T). Comparing the V.mat and V.mat0 for some images reveals no difference up to the 4th decimal, whereas for others there is a big difference at values in the 4th column (see below for example). My aim is to do VBM using DARTEL. I am not sure I understood how to deal with this - should I try some other utility to convert the DICOM files (are there any you would recommend?). Is it right that I cannot use DARTEL for VBM while N.mat and N.mat0 differ like this?
Thanks very much for help in advance.
Kind regards,
yannis
