1. Start DigitalMicrograph

2. From python command line

from pyscope import dmsem
d = dmsem.GatanUltraScan()
d.getImage()

pyscope test result array

You should expect these to run without error. The getImage() command should give a 2D numpy array like

array([[1000, 3400, 2300, ..., 1000,1200,3000],
         [1000, 3400, 2300, ..., 1000,1200,3000],
         [1000, 3400, 2300, ..., 1000,1200,3000],
         ...,
         [1000, 3400, 2300, ..., 1000,1200,3000],
         [1000, 3400, 2300, ..., 1000,1200,3000],
         [1000, 3400, 2300, ..., 1000,1200,3000],dtype=int16)

The number and dtype depends on the camera.

a.shape command should give a tuple of the camera dimension matching your camera.
For example, (4096,4096)

If you use python shell to do this test, some of the error will cause the shell window to close immediately. Use Python IDLE instead in that case
