Processing the images#

Now that we have opened our files, we can (finally!) do something with them.

In this case, we will apply a gaussian blur to all of the files, with a given sigma.

run("Gaussian Blur...", "sigma=2");

Add this file to your script. Think about where in the script this should go, and why.

folder = "path/to/file";
file_list = getFileList(folder);
number_of_files = file_list.length;

for (i=0; i<number_of_files; i++){
  file_path = folder + File.separator + file_list[i];
  open(file_path);
  run("Gaussian Blur...", "sigma=2");
}

Now if you run this script it will open the images, and once each file is opened, apply a gaussian blur to the image.

However, rather than just applying this to every image and keeping them all open, let's instead save each file after we apply a gaussian blur, and then close it before we open the next in line.
