Can you upload a single dicom file to me? One should be enough

Thanks, but the orientation shift appears as a skew. Also, we don't have any fiducial markers for this group of scans so it would be a little tricky to confirm the correct application of -out_orientation. I would rather let mri_convert handle this from the .IMAs.
Is there any additional information I can provide from from the .IMA header etc that could shed some light on why mri_convert is behaving in this way?
Thanks, Paul

Not sure if this helps, but you can alter the output orientation using the flag "--out_orientation" followed by LIA (for example). Maybe the input file needs to be in a specific orientation before it can be converted properly.

Using: mri_convert -it siemens -ot mgz 1.IMA test.mgz I get the error message: does not contain a Siemens ASCII header has this file been anonymised? ERROR: cannot unpack mosiacs without ASCII header The .IMA files have been taken straight from the scanner console. If I try: mri_convert -it dicom -ot mgz 1.IMA test.mgz this creates the .mgz, however there is an orientation shift and a vertical stripe artefact appears in the sagittal view (please see attached) when compared to the original .IMA. Any suggestions on how to convert the Siemens .IMA files correctly?
