Bug #4678
openz height go to another
0%
Description
when restart leginon with queue and restart data collection, the stage z goes to the wrong value when submitting the existing queue.

Leginon is designed to reacquire sq image through "Target Adjustment" node after "Z Focus" node adjusts the stage height. This allows a record of the new Z height with the new version of the image. When "Hole" node receives a TargetList, it looks up the most recent version of "sq" image and adopt its height.
There were two settings problems in this case:
1. In "Hole" node, Target Adjustment was set to use no ancestor where it should have been "one" so that "Target Adjustment" would perform its task.
2. In "Target Adjustment", the settings for minimal mag was set at the default 300x. With today's direct detector, the "sq" mag is possibly lower. In the two cases where this happens, they are 280x and 165x.
commit change of the min mag to 140x.
Will write a validation code to warm user if using the bad combination of the settings.
