Binning=2x2 (Counted mode)
- Start DigitalMicrograph
- From python command line or IDLE:
import pyscope.dmsem k = pyscope.dmsem.GatanK3() k.setBinning({'x':2,'y':2}) k.setExposureTime(200) k.getImage()
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
Testing frame saving¶
You can continue the test above by saving frames, too.
k.setSaveRawFrames(True) k.setExposureTime(200) a=k.getImage() a.shape* The last command should give you the shape of the summed image, and the frame movie should show up on your frames directory
