1. Open the STEMcor tool from Menu "temDM: STEMCor.

Linear correction (section "linear drift correction" in STEMcor tool):
2. Check the "onFFT" box. 
3. Click first at "16.23.48orig.dm3" and then at "16.24.32rot.dm3" image, then press the "correct drift" button.

Non-linear correction (section "non-linear drift correction" in STEMcor tool):
4. Click at "16.23.48orig.dm3" and then at "16.24.32rot.dm3" image, then press "sticking point" button. You see two images - left and right - coupled in one panel.
5. Move the red marker in the left image at the nearest atomic column (the right green marker will move synchronously but unlikely land accurately at the column because of STEM distortions).
6. Move the green marker at the corresponding column (note that the red marker stays, the synchronization work in one direction only). There are two sublattices here, red and green markers should be at the columns of the same sublattice.
7. Press "confirm" button in the floating dialog.
8. Press "correct" button.

This example appears to be sensitive to the choice of sticking point position. Therefore we provide the images where the sticking points are predefined.Then most of steps can be skipped.
 
7. Click at "16.23.48orig LDcorrected.dm3" and then at "16.24.32rot LDcorrected.dm3" image, check the position of the red and green markers but dont change it. Press "Cancel".
8. Press "correct" button.
