See my response to your question yesterday.

Subject: [FSL] DICOM to nifti conversion difficulty
I have been using MRIConvert to convert my DICOM files to nifti format. I
have some DTI DICOM data from a that are a series of 15 slices for each of
my 25 gradient vectors (390 slices in all, including the b0 scan). When I
try to convert these files to a single 4D nifti file, MRIconvert only takes
the last 15 slices and outputs a single 3D volume. I also have some DTI data
from a Siemen's machine that is in mosaic form (that is each DICOM file in a
given DTI series is a mosaic of slices) and MRIconvert seems to have no
trouble converting these into the appropriate 4D nifti file.
Has anyone else encountered this problem?
I could divide the 390 DICOM files into 15-slice volumes "by hand," convert
each volume separately and manipulate them using the fsl utilities. However,
that seems cumbersome and I thought the DICOM mosaics were a recent
development so this older converter should be able to handle my hefty stack
of data, right?
thanks!
