What is your exact command line?
The version of the file that you gave me definitely has an ascii header, and I don't get that warning when I convert. What version of FS are you using on what platform? To check whether that file has an ascii header, run
mri_probedicom --i MR.1.3.12.2.1107.5.2.19.45306.2014091812330393354083931
There should be a line like below
### ASCCONV BEGIN

Hi Doug,
That’s weird because I can’t convert it using only mri_convert, here is the error I get :
WARNING: file /Users/ismailkoubiyr/Documents/PFE/Tracula/dti/3T2/MR.1.3.12.2.1107.5.2.19.45306.2014091812330393354083931 does not contain a Siemens ASCII header has this file been anonymized? ERROR: cannot unpack mosiacs without ASCII header
Any idea why ?
Best,
Ismail

I was able to convert it fine with mri_convert MR.1.3.12.2.1107.5.2.19.45306.2014091812372179441003292 output.nii.gz If I included -it dicom, the conversion did not have an error, but the output had only one slice. Since these are mosaics, they need the Siemens ascii header which is ignored with -it dicom. So ... don't use -it dicom

Hi Doug,
It is still an issue. I uploaded the DICOMs to you. Hope it could be useful. Thanks.

Is this still a problem? If so, can you upload the dicom files to our file drop?
