MATLAB: Hoe to use BRAT Dataset? It is in .nii format. I want to store it in .mat files. How to do it

brain segmentationbrat dataset

[V info]=ReadData3D(file .nii);

After this V has 256*256*155 matrix.

How to read the image?

I think it likely that you have already read the images. .nii files often have multiple slices stored in the same file. Your slices are V(:,:,1), V(:,:,2), V(:,:,3) and so on.

If you have R2017a or later, you could view them using

 volumeViewer(V)

You can do all of this with core MATLAB.

Here is an example of reconstruction of a wooden dowel and visualization.

You will be using 3-d matrices

T(:,:,1) = m %Pronounced Matrix T, all rows, all columns, layer one equals m

The slice.m command will also be useful. You might be interested in sliceomatic also.

MATLAB: How to convert file format from .mat to .nii format

Dear All The following code is to create .nii file from 16mat files.

what I need is to do opiste. Svae .nii file to 16 mat files.

files=dir('*.mat');
A=[10:16 1:9] % this is because the volume not in the right order. 
for f=1:16; 
g=A(f); 
load(files(f).name);
M0vol(:,:,g)= M0; 
t2starvol(:,:,g)=T2star; 
r2starvol(:,:,g)=R2star;
end
nii=make_nii(M0vol); 
save_nii(nii,'N_144_M0.nii');
nii=make_nii(r2starvol); 
save_nii(nii,'N_144_R2star.nii');
nii=make_nii(t2starvol); 
save_nii(nii,'N_144_T2star.nii');
