Description
- If a stage movement occurs after exposure targeting has been set up (eg. ZLP alignment), transformmanager checks that stage is in the correct place and does any needed correction
- This is done using the targeting mag, so it needs to take an image at that mag
- currently it stays at that magnification, then goes back to the preset manager to continue imaging
- If wait time is 0 in preset manager, there may not be enough time for the beam to stabilize after changing back to high-mag imaging, leading to a degraded image
- this change sends the original preset back to the microscope and then pauses before continuing image
- pause time is still set in the "settings" menu for this node
- 5s is good for the NYU Krios
Updated by William Rice 5 months ago
- if a Leginon session is restarted without a preset being sent first, the pause causes an error since it does not know which preset to store
- this minor modification prevents this problem from happening by checking if getting the current preset works or not
- if no current preset is found, the pause is disabled
