Description

AutoZLP can fail in different ways if the reference area is not clear of obstruction. Sometimes, GMS function won't even return. Doing a test on the intensity can reduce crashing.

Actions #1

Updated by Anchi Cheng about 4 years ago

The threshold is determined by images already saved with the preset. It also has a minimal threshold of 5.0.

Actions #2

Updated by Anchi Cheng about 4 years ago

  • Target version changed from Appion/Leginon 3.5 to Appion/Leginon Future Version

This does not work well because the preset comes often from Focus node preset sequence and therefore either fc or fa. There are usually no image saved for it. Bright image values tend to come from very different imaging parameter. Also badly aligned ZLP image can be very low intensity, too.

Left at minimal threshold for now. It does prevent calling ZLP alignment when camera is in error state which would have stalled the call, too.

Actions #3

Updated by Anchi Cheng about 4 years ago

  • Target version changed from Appion/Leginon Future Version to Appion/Leginon 3.5

Changed to use the first test image to determine the threshold. This should work better.

Actions #4

Updated by Anchi Cheng about 4 years ago

  • Target version changed from Appion/Leginon 3.5 to Appion/Leginon 3.6

Diabled in 3.5 because its results is still wrong in certain condition.
