DWIConvert requires all files to be from the same sequence. If you have SlicerDMRI extension installed, the DICOM Diffusion Volume plugin may be able to sort your files (but does not support all scanners/models). If you are using an older Slicer version, please try a recent nightly build.

If that does not help, then please post your scanner model and Slicer version.

I have SlicerDMRI extension but there is no DICOM Diffusion Volume plugin.

GE 1,5T, Slicer - 4.8.1

It is available in recent SlicerPreview (nightly) builds.
