h1. Queuing Example 3 - Both Exposure and Hole Targeting 




 MSI-Tomography application is an example of such queuing set up. It is also the useful 
 when energy filter is used. It is chosen so that the microscope stays at the same presets as 
 long as possible to obtain all the images so that LM preset sq will not need to be used once 
 tomography data collection starts. 



 h2. Configuration 





 *    /Square/Toolbar/Setup/Wait for a node to process image = no 


 The "no" setting saves time by acquiring images while holefinder and YOU are picking 
 targets. 


 *    /Hole Targeting/Toolbar/Setup/Queue up targets=yes. 


 *    /Hole Targeting/Toolbar/Setup/Allow user verification of the selected targets=yes, 
 if desired. 


 *    /Hole/Toolbar/Setup/Wait for a node to process image = no. 


 *    /Exposure Targeting/Toolbar/Setup/Queue up targets=yes. 


 *    /Exposure Targeting/Toolbar/Setup/Allow user verification of the selected 
 targets=yes, if desired. 







 h2. Operation 





 *    Select square targets on grid atlas and submit as usual. 


 *    All sq images will be acquired while "Hole Targeting" finds the targets on each sq 
 image since waiting in "Square" node is off. Note that since the square node acquires 
 images continuously, both hole finding and acquisition may compete for processing and 
 memory time. If it affects your interaction with the program, just wait for the 
 acquisition to complete. 


 *    If you have just acquired many (such as 50) sq images in LM mode, the microscope 
 has stayed in LM for a long time. It is advisable to set the instrument to one of the 
 preset in HM mode as soon as the acquisitions are completed and check for possible image 
 shift inconsistency between presets. If energy filter need to be on for higher 
 magnification imaging, do so now. 


 *    If user verification is turned on in "Hole Targeting", the targets should be 
 submitted using "submit"<inlinegraphic 
 fileref="http://emg.nysbc.org/software/leginon/images/icons/play.png" format="PNG"/> 
 tool. 


 *    The Queue is submitted and processed only when "Submit Queued Target"<inlinegraphic 
 fileref="http://emg.nysbc.org/software/leginon/images/icons/send_queue_out.png" 
 format="PNG"/> tool is clicked. 


 *    Repeat the same target selection and submission process at "Exposure Targeting" 
 node. 


 *    In case when leginon crashes during queue processing, the data acquisition should 
 be resumed by "Submit Queued Target"<inlinegraphic 
 fileref="http://emg.nysbc.org/software/leginon/images/icons/send_queue_out.png" 
 format="PNG"/> in "Exposure Targeting" node first. If nothing happens, it means the 
 queue in that node is empty. In that case, repeat it in "Hole Targeting" to 
 resume. 







 h2. Interruption 



 Once the queue is submitted there are several modes of interruption 


 *    If leginon crashes during queue processing, the data queue acquisition can be 
 resumed by "Submit Queued Target" in first the "Exposure Targeting Q" node, then if 
 nothing happens, in the "Hole Targeting" node. 


 *    Queued targets from "Hole Targeting" can be paused in "Hole" node with "pause" 
 button and is <link linkend="MSI_pause">recommanded for the liquid nitrogen refill of 
 the side-entry cryo stage</link>. 


 *    The "Abort" button<inlinegraphic 
 fileref="http://emg.nysbc.org/software/leginon/images/icons/stop.png" format="PNG"/> 
 in "Hole" node aborts the acquisition of the remaining targets from the same parent "hl" 
 image and proceeds to process targets from next square in the queue. 


 *    The "Abort Queue" button<inlinegraphic 
 fileref="http://emg.nysbc.org/software/leginon/images/icons/stop_queue.png" 
 format="PNG"/> in "Hole" node aborts all remaining targets in the queue. 


 *    Exposure targets are paused and aborted in a way similar to the queued Hole 
 Targets.
