Hi Félix,<div><br></div><div>I agree that doesn't sound too good. I don't understand how this could happen, unless the series numbers stored in the DICOM header for each file are also in the wrong order - this is what MRtrix uses to order the volumes. My first guess would be that this is the problem. You can easily check by running read_dicom on each file to see what series number it reports, and whether they match the order you expected. If not, I'd need to take a look at the data - any chance you could send me these files? </div>

<br>
I am trying to create a 4D Nifti volume from multiple Siemens DICOM<br>
mosaic. The XYZ axis seem to be fine. However, slices along the time<br>
axis are presented in random (?) order.<br>
<br>
I reproduced the issue with four original DICOM mosaic: 000[1-4].dcm.<br>
I convert them to 4D Nifti using mrconvert. The resulting time axis is<br>
ordered as following: 0001, 0004, 0002, 0003, which is not the<br>
expected behaviour.<br>
<br>
Do you have any idea what's going on?<br>
<br>
