im saving two images but how do i change their names ?

2 views (last 30 days)
Hi, Basically the code saves the two images, but how would i go about giving each image a name? because atm they are overwriting each other because i haven't assigned a name to them yet.
Savesinog = uigetdir(workdir,'Please select the destination directory');
imagetype= ['.tif']
FileName = fullfile(Savesinog,imagetype)
imwrite(sinog_2,FileName);
imwrite(iradonsinog,FileName);

Just add a name into the fullfile call. You have a directory and an extension at the moment with no filename.
FileName = fullfile( Savesinog, someFilename, imagetype );

fullfile does not magically append the file extension, this has to be done independently of fullfile:
FileName = fullfile(Savesinog, [someFilename,imagetype]);
