[Mrtrix-discussion] Question about convert from nii to mif

[dti mic]

Dear MRtrix,

I am trying to convert a 4D dwi data set in NIFTI format (converted from
DICOM using dcm2nii) into mif image. The error message I got is:

"mrconvert: memory-mapping failed for file "./dwi.mif": Invalid argument".
The input image (the name of which is "P481210209_xyz_eddy_Ave.nii", a
little bit long and wired I know) in nii format can be well accessed by FSL
and MRIcron or MRIcron. Any idea of what I can do to fix this issue? Should
I try some more options in the mrconvert command?

Many thanks for your help in advance!
