Hi everyone,

I have some problems trying to run TRACULA on some DWI data. It is a mosaic 
Siemens DWI. I first converted the DICOM files with dcm2nii to get the bvec and 
bval files.
Then I run the trac-all -prep -c command and I get the following error :

WARNING: file /My/path/to/dicom does not contain a Siemens ASCII header
has this file been anonymized?
ERROR: cannot unpack mosiacs without ASCII header

I tried to unpack the mosaics with gdcmtar, but I got the same error.

Thank you in advance for your help,

Ismail
