I used the same command line as you did. And when I check with mri_probedicom I can see the ASCII header.
Here is the version of FS I am using : freesurfer-i386-apple-darwin11.4.2-stable5-20130514 Do you think it might be related ? Thanks again.

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 On 07/19/2016 01:16 PM, Koubiyr, Ismail wrote: 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?
