Convert .MAT to .DAT in matlab for a 2D Image

Hi,

I've been trying to convert .Mat files to .Dat file in MATLAB. Actually the codes takes .Dat file of an image and then denoises it.

I have .MAT MRI images and I'm unable to convert it into .DAT

Is there any way of changing the code if the first option isn't feasible?

Thanks for the response x

.dat is a generic file extension; it is used for any data format at all. You need to indicate which software the output needs to be compatible with.

It should be compatible with Matlab. The code takes input in .dat file extension (in the form of 2D image) but i have .MAT file extension of 2D image. So i need a way for converting .mat to .dat

It's easy to convert from .dat to .mat file extension.

What existing code is it that takes a .dat file extension?

Because .dat files can be anything, we need to know what format the existing code expects. In particular we need to know how the code expects the size information to be represented, and we need to know whether the code expects data to be stored "across" or "down" matrices, and we need to know how it wants the color planes to be interleaved if it supports color planes.

load 'lena_clean.dat'; 
setup_path;
% stats.errs = cell(2,1);
% stats.Fx = cell(2,1);

% read data, assume size 512x512
fprintf('Reading image: %s\n', dataset );
image_noisy_file = [dataset,'.dat'];
image_clean_file = [dataset,'_clean.dat'];
image_sol_file = [dataset,'_sol',num2str(model),'.dat'];

img = load(image_clean_file, '-ascii');
noisyImg = load(image_noisy_file, '-ascii');
if exist(image_sol_file, 'file')==2
    ref_sol = load(image_sol_file, '-ascii');
else
    ref_sol = load(image_noisy_file, '-ascii');
end

This is the part of the code which takes .dat 2D images, 512x512 is the size. It doesn't support color planes.

matname = [dataset '.mat'];
datastruct = load(matname);
fn = fieldnames(datastruct);
outname = [dataset '.dat'];
data_to_save = datastruct.(fn{1});
save(outname, 'data_to_save', '-ASCII');

Thanks Alot Walter!!

Bless you.
