Hey guys, I was wondering if you could help me out.
I'm having some problems opening medical images in MATLAB.
Their extension is .nii and I need them to be .m ; is there any simple form to do the conversion?
Thanks
JM

niftiread() from R2017b.
There were File Exchange or Third Party contributions for reading nifti images before R2017b.

clc;
clear all;
file = dir('*.nii');
len = length(file);
for i = 1:len
nii_file = file(i).name;
nii = load_nii(nii_file);
img = nii.img;
mat_name = strcat('img_', int2str(i), '.mat');
save(mat_name);
load(mat_name);
figure(1)
subplot(4,5,i), imshow(img(:,:,1),[]), title(i)
end

Why do you load() back on top of what you just save()'d ?
