Hi everybody, I have a 3D image stored in a .raw format, 32 bits floating point, uncompressed. The dimensions are 288x288x400. How can I open this image in Matlab?
Thanks in advance, Joaquim Costa

Hi, I am also trying to import an image in .raw format. My question is that, how did you know the dimensions and other details of your image?

fid = fopen(FileName, 'r);
if fid == -1
error('Cannot open file: %s', FileName);
end
data = fread(fid, 288*288*400, 'float32');
fclose(fid);
data = reshape(data, [288, 288, 400]);

How are you doing the displaying? After you display, is get(gca, 'YDir' set to normal or reverse?

@Joaquim: How do you apply flipud on a 3D-array? Please post you code instead of describing it.

R2014a redefines flipud, fliplr, rot90 to be able to handle arrays with multiple dimensions.
