1. Open the stand-alone STEM Corrector tool.

2. Click "LOAD" button at the left-lower corner. Holding CNTR, choose both "16.23.48orig.ser" and "16.24.32rot.ser" files. Read the names of loaded images at the top of the tool, ensure that the original orientation image is at the left while rotated one is at the right. If it is not the case, switch them by clicking  the "Exchange" button in between images.

3. In the bottom of the tool disable "use FFT". Although these images are of atomic resolution, the simple cross-correlation works better. Press "LINEAR". 

4. The linearly corrected images appear. If you wish to see them in the same orientation, click the knob rotate under the right image. The correction is rather small in this case but the images sizes are changed. Click the button "Frames" in the lower part of a band between the images to check different sizes of frame.

5. Non-linear correction is currently not implemented.
