Dear Doug Yes, the data is straight off the scanner, I don't think it has been manipulated, but I will check. When I run the the command suggested I get the below error message: mri_convert –it dicom -ot mgz 1002/IM-0001-0001.dcm 1002.mgz mri_convert –it dicom -ot mgz 1002/IM-0001-0001.dcm 1002.mgz
mri_convert: extra arguments ("1002/IM-0001-0001.dcm" and following)
type mri_convert -u for usage
I am not quite sure where I am making an error. Cat

Is it straight off the scanner? It does not have the siemens ascii header which usually means that it has been manipulated in some way. You can try using mri_convert with --it dicom doug

has this file been anonymized? On 05/23/2013 12:39 PM, Cat Chong wrote:
Hello Experts, I am trying to run the mri_convert command prior to the recon-all command on Siemens T1 dicoms (as suggested in the archives). I am using freesurfer version: freesurfer-Darwin-lion-stable-pub-v5.3.0, Mac OS X Lion 10.7.5 I am using the command below: mri_convert -it siemens_dicom -ot mgz 1002/IM-0001-0001.dcm 2001.mgz Below is the command line error I receive, it is a similar error I receive when I try to use the command recon-all on the Siemens dicoms. I have used freesurfer before on GE dicoms and never had a problem running recon-all. Is this error message particular to the Siemens dicoms, and would you be able to tell me how to proceed?
