writeFileNifti doens't write complex data correctly #296

Open cecilyen opened 6 years ago

cecilyen commented 6 years ago

I have a 4D single complex array in Matlab. When I try to use writeFileNifti.m and writeFileNifti.mexa64 to write the NIfTI file, the result NIfTI file is not correct. It seems the matrix is messed up.

Ps. I am using Matlab 2018a with CentOS 6.9. writeFileNifti.m and writeFileNifti.mexa64 were downloaded on 6/12/2018 from here.

I just realize that I was only using writeFileNifti.m, not the mex version. writeFileNifti.m internally calls Shen's NIfTI codes. If I used Shen's maek_nii and save_nii, I could get correct complex NIfTI files. So, the issue is in writeFileNifti.m

did you try niftiWrite, which calls the mex file writeFileNifti?
