DTI, averaging of b0 images

Thanks for the quick reply.

b-value is 1000 and 30 directions. Unfortunately Other scans will be at 10 directions, but still appears to have good results

The details of the study are complex, but the simple story is that we suspect there is near anatomical absence vs complete dysfunction of superior fasciculus pathways from the occipital lobe (based on volume loss in anatomical T1 /t2 imaging with additional evoked potential recordings). So the issue is providing evidence that the pathway is present (or not). With the same parameters (start and stopping thresholds modified to be lowered), we get excellent results for occipital lobe to temporal lobe, corpus callosum, cortico-spinal, even cerebellum looks great. So sensitivity is important here.

With Dcm2nii I get an error (I have replaced subjectID stuff with XXXXXXX)

Command ‘[u’C:/Users/jkelly/AppData/Roaming/NA-MIC/Extensions-28257/SlicerDcm2nii/lib/Slicer-4.10/qt-scripted-modules\\Resources\\bin\\dcm2niix’, ‘-1’, ‘-d’, ‘0’, ‘-f’, ‘tmp7jvaws’, ‘-o’, ‘C:/Users/jkelly/AppData/Local/Temp/Slicer/__SlicerTemp__’, ‘-e’, ‘y’, ‘-z’, ‘y’, ‘O:\\Slicer\\SM_Disconnect\XXXXXXX’]’ returned non-zero exit status 2

fyi, tried DICOM patcher - gives me

I’ll try other things…
