Hi Nick,
I am not sure what do you mean by average, but you definitely need to remove it, especially if you are not sure what the volume is. Fdt tools will use all volumes contained in the input data file.
Cheers

I wonder, instead of removing this volume from the 4D-niifti file, could I just set bval = 0 for this volume when calling dtifit? Ot do dtifit make use of the non-gradiet volumes as well? There is, of course, a real zero-volume, the first volume, as well.
