Hello,
I have an image database, i process them through a for loop, i want to save the output processed images in anther folder, i have the following error when i trying to do that:
Error using imwrite
unable to open file " ********.bmp" for writing. you might not have write permission
the code i have used is:
SNLImagepath='F:\SNL_images\';
FileName = fullfile(savepath, sprintf(ImageName,ext));
imwrite(a, FileName);

You gave the wrong path. "savepath" is a built in function, and you're trying to call it when you call fullfile()! You should pass in SNLImagepath, not savepath. Plus you're calling sprintf() incorrectly -- you didn't give it a specification string.
Try this:
SNLImagepath='F:\Biometrics\Eman\Eman_test_SNL_Gabor\SNL_images'
FileName = fullfile(SNLImagepath, sprintf('%s%s', ImageName,ext));
imwrite(a, FileName);

MATLAB does NOT see the % symbol as a comment when it's embedded in a string, like I did here. You might want to learn how to use format specifier strings since it's common to all programming languages. That's the protocol where you use %, some numbers, and a letter that indicates the variable type (f, d, s, etc.).

Have you correctly given the permission to the folder you are writing?
Once try this,
savepath = 'C:\Some_dir\Some_folder';
FileName = fullfile(savepath, sprintf(ImageName,ext));
imwrite(a, FileName);

you need to edit the line
FileName = fullfile(SNLImagepath, sprintf(ImageName,ext));
