Dear all,
I have file outVol.mat (can download thru link: https://drive.google.com/file/d/10O7ou3lcP_YWXzsYhUL6N_9xnoOQrJ_S/view?usp=sharing).
The size is 135x135x74.
I want to convert it into .nrrd format. Below is my command. The attached nrrd function attached.
But I little bit confuse. How to get the same size when convert into .nrrd format? because I get the wrong size
Anyone can help me?
clc
clear all
close all
img = load('outVol.mat');
% Set pixel data
[x,y,z] = meshgrid([-10:10],[-12:15],[-8:6]);
img.pixelData = x/3+y/4+z/2;
% Define origin, spacing, axis directions by a homogeneous transformation matrix:
img.ijkToLpsTransform = [ 1.2 0 0 10; 0 1.2 0 12; 0 0 3.0 -22; 0 0 0 1];
% Enable compression
img.metaData.encoding='gzip';
nrrdwrite('testOutput.nrrd', img);

Hello,
Instead of the following line of code:
img = load('outVol.mat');
You need to access the outVol field of the img structure to retrieve the image data. Here's the modified code:
imgData = load('outVol.mat');
img = imgData.outVol;
This is because img is a structure containing multiple fields, including the outVol field that holds the actual image data
