volumewrite

[Marie Smith]

Hi,

I am trying to output the results of sourceinterpolate to analyze
format to read in afni / spm2. The volumewrite function does seem to
do this but the orientation of the output mri is not correct when
viewed in spm2 / afni (coronal is axial and rotated 90degrees,
sagittal is coronal also rotated and axial is sagittal also rotated).
I have checked and it seems to display correctly in sourceplot (in
that it matches the images shown in the tutorial documentation for
beamforming).

I am selecting cfg.coordinates = 'cfg' and cfg.filetype = spm in
volumewrite and leaving the rest to the defaults.
Could there be an orientation error coming in from somewhere and how
can I fix it ?

Also on a related point, i also tried cfg.filetype = 'analyze' and
got quite a different output when viewed in spm. The slices seemed to
have been rotated in some way in addition to errors in the orientation.

Any advice would be appreciated,

Marie
