Hi everyone,

I’m reposting my problem if someone could help me I would really appreciate it.

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.

P.S : DTIFIT works on FSL (FDT) but gives a poor quality in the reconstruction not as the one expected with Tracula.

Thank you in advance for your help,

Ismail
