Dear MRtrix,<div><br></div><div>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:</div><div><br></div><div>"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?</div>
<div><br></div><div>Many thanks for your help in advance!</div><div><br></div><div><br></div>
