Hey Wasna,

The niftiread() function can help you do that very easily.

The niftiread(your_file), function reads and returns the volumetric data of your file in the specified variable which you can modify according to your needs.

Below is a code snippet for your requirement.

% Specify the path to your NIfTI file 
niiFilePath = 'path_to_your_file.nii'; 

% Read the NIfTI file 
niiData = niftiread(niiFilePath); 

% Convert the 3D matrix to a single array 
% This step converts the shape of data to a single array 
singleArray = niiData(:); 

% Specify the path for the .mat file 
matFilePath = 'output_file.mat'; 

% Save the data to a .mat file 
save(matFilePath, 'singleArray'); 

Here is a link to the documentation for niftiread():
