bitmode	Bits per pixel [4|8|16|32]
fileIndex	Current file acquisition index
detshape	Geometry of the entire detector
shape	Geometry of the current port streamed out
size	Size of image of current port in bytesout
acqIndex	Frame number from the detector (redundant)
frameIndex	Frame number of current acquisition (Starting at 0)
progress	Progress of current acquisition in %
fname	Current file name
data	1 if there is data following 0 if dummy header
completeImage	1 if no missing packets for this frame in this port, else 0
frameNumber	Frame number [From detector udp header]
