Note: This node works only with NRAMM grid loading robot. You should modify it to suit





    44
    
    
    
your robot for the above functions. As long as it has the same event binding to perform the





    45
    
    
    
following functions, your custom node can be used with any Leginon acquisition





    46
    
    
    
sequence.
