Gatan on Windows-32¶
See Gatan on Windows-32 with TecnaiCCD.dll- This is only known to work for Gatan camera associate with FEI microscopes. For JEOL microscope, See Gatan on Windows-32 with dmsem
Extra Package and Installation¶
program/package | notes |
---|---|
TecnaiCCD.dll |
Program | package web site | local copy of win32 installer |
comtypes 0.6.2 | http://sourceforge.net/projects/comtypes" | comtypes-0.6.2.win32.exe |
Register TecnaiCCD.dll (It may have been registered already)¶
- From the command prompt, run the following commands. You may need to enter the full path of the dll:
REGSVR32 TecnaiCCD.dll
instruments.cfg¶
[camera] class: gatan.Gatan zplane: 50 height: 4096 width: 4096
- height and width depend on your specific camera
see instruments.cfg z plane configuration for more explanation.
If you have more than one camera controlled through DM, you need to find its id and use class gatan.Gatan0 and gatan.Gatan1 etc in the configuration to distinguish them and assign different zplanes so the higher ones can retract when the lower one is asked to acquire image. see #2201 for history of this issue
Setup¶
- Set camera configuration to give the standard Leginon orientation.
- Set the shutter configuration in DM to protect the specimen when camera is not taking images
Testing with pyscope¶
In python command
from pyscope import gatan g = gatan.Gatan() g.setExposureTime(200) g.getImage()
You should get a bunch of numbers in a numpy array.
Programs to open before Leginon Client: Digital Micrograph¶
