Online uncaging analysis does not work

[meganbkratz]

The following error occurs when online uncaging analysis is enabled. (The NIDAQ Warning occurs whether or not the uncaging analysis is enabled, so may or may not be related.

NIDAQ Warning:
('Clock rate specified is so high that it violates the settling time requirements for the acquisition.\n\nReduce the clock rate, or the accuracy of the measurement might be compromised.', '')
Traceback (most recent call last):
  File "C:\Documents and Settings\Experimenters\luke\acq4\lib\modules\ProtocolRunner\analysisModules\Uncaging\interface.py", line 61, in newFrame
    self.currentProt.addFrame(frame)
  File "C:\Documents and Settings\Experimenters\luke\acq4\lib\modules\ProtocolRunner\analysisModules\Uncaging\interface.py", line 180, in addFrame
    camInfo = frame['result'][camDev]['frames'][self.state['frame1Spin']].infoCopy()
KeyError: None

Earlier in this function is the line:

camDev = self.ui().cameraDevice()

This is setting camDev to None (which creates the KeyError). This is happening in an if/else block at line 136 in the same file.

Probably just caused by not telling the uncaging analysis module what camera
device to use (?) It would be nice if this printed a useful error message
and handled the exception gracefully.
