RE: Reading MRI images with nifti_image_read()
Hi Rick,
Thanks a lot for your reply.
When I print out the nim->datatype, it is 2.
In addition, I have used the SPM MATLAB package to read the same .nii file, and the value for each voxel should be a float. But when I print out the intensity value of each voxel with the niftilib, the results are like the follows:
0.00
0.04
3172.52
219338047488.00
55137620.00

13076.84
48.81
How can I obtain the voxel intensity value correctly? Really appreciate it!
