Transition from Krios to EFKrios

Added by Christopher Lilienthal about 4 years ago

Hello,

We have been running Leginon on our Krios for some time while it did not have an energy filter installed on it so the relevant instruments.cfg file content is below:

[TEM]
class: fei.Krios
cs: 2.7e-3

Now that we have an energy filter installed on the microscope should I be configuring the instruments.cfg file as follows?

[TEM]
class: fei.Krios
cs: 2.7e-3

[EFTEM]
class: fei.EFKrios
cs: 2.7e-3

Or should I remove the legacy configuration so the instruments.cfg file contains just the one instrument?

[TEM]
class: fei.EFKrios
cs: 2.7e-3

If it helps the only camera configured in Leginon will be a K3 that is attached to the GIF.

Thank you for your time.

In general, unless there is need to change TEM instrument during a session, such is the case with Diffraction mode disguised as a separate TEM, you should only include the tem you use in instruments.cfg

In this case, we do not control through leginon the activation of EF-TEM on the scope. Therefore, you should remove the legacy configuration.

Hi Anchi,

Thank you for the quick reply. That explanation makes sense.
