Which MATLAB release are you using?

i use Matlab R2015a

[Walter Roberson]

niftiread https://www.mathworks.com/help/images/ref/niftiread.html was introduced in R2017b.

is there a way to display the images in .NII file?

[Walter Roberson]

Only by reading them and displaying them. There is no tool available that will "preview" .nii files somehow.

Answer 2

is there not a solution with Matlab R2015 ?

[Walter Roberson]

No. There was no built-in way to read NIFTI images in R2015* . There are multiple File Exchange contributions that can deal with nifti files, but MATLAB itself did not add anything until R2017b.
