Click the Step-by-step' box (green tick appears in it).
Open the (first) image file with DrawWing.
Click on 'Wing/Apis Junctions' (or use the button on the toolbar, or shortcut Ctrl+a)
Adjust the threshold so that the wings are solid black on a white background and click OK.
DrawWing now presents you with the first wing. Adjust the threshold as necessary so that the veins are clear - it is better that they are slightly too dark rather than too light. Click OK.
DrawWing now shows the wing with the landmarks positioned to the best of its ability.
Check that numbers 0 - 6 and 18 are roughly in the right places. If any have not been placed, drag them into position but do not worry about accuracy at this point.
Drag the magnification slider on the right-hand side of the screen upwards to its maximum position.
Use the mouse scroll wheel to move up to the top of the image and check landmark 6.
Hold down the Alt key and scroll 'up' again. This causes the image to scroll across the screen. Move landmark 5 on to the junction of the veins.
Keep the Alt key down and scroll across to check landmark 18.
Keep the Alt key down and scroll back to check landmark 2.
Now release the Alt key and scroll down to check 0, 1, 3 and 4. 0 and 3 will almost certainly need moving to the centre of the vein junctions.
After completing each wing click on the 'Next step' button (Green arrow), say 'yes' to save the wing data.
Another wing will then be presented until all the wings in the scan have been processed.
If the wings were scanned in several batches, repeat the process for each scanned image.
