Oh, so it is just a visualization problem and not carried through into the data file. Viewing as you suggested, got rid of the problem. Thanks so much for the help! Angela

Hi Angela,
this may just be a visualization artifact of the resampling to RAS coords. You can try:
view->anatomical sampling->main volume->slice
which will show the raw (unoriented) data, or
view->anatomical resampling->main volume->trilinear
which will use trilinear interpolation instead of nearest neighbor.
cheers, Bruce

I am using mri_convert to convert some MR images in dicom format to 001.mgz. When I view 001.mgz, using tkmedit, each transaxial slice looks like it is pieced together from the wrong slice of the original transaxials. As I progress from one slice to the next, this band moves across the image.
It shouldn't look like this, should it?. Is there something I can do to prevent this when converting to mgz format?
