Dear Juergen,
the Volumes toolbox has a utility "Split volumes" and "(De)Interleave
volumes" that may help you, if there are 2 or more complete 3D datasets
put together in one NIfTI file. If your slices are spread over multiple
NIfTIs, then you should consider sorting this out in your DICOM data or
during conversion. You will have to modify DICOM header information to
match the correct Series/Acquisition/Image # using e.g. CTN Dicom tools or
DICOM toolkit (dcmtk) software. Alternatively, read in all unsorted images
using spm_read_vols, and do the sorting in MATLAB.
