I tried this command, successful..
clc
clear all
close all
sz = [128 128 128];
fname = 'ect_it2.img';
fid = fopen(fname);
data = fread(fid,'*float'); % assuming uint
fclose(fid);
% this is blindly devectorized
% may still be transposed, but i can't tell due to symmetry
% note that data is binarized on a [0 1000] scale in uint16
% so if viewing in a denormalized manner, it'll just appear black
% normalize or rescale it as needed
data = reshape(data,sz);
imshow3D(data)
