Description

Happened to Natalia. Exception was raised in this case in the terminal as:

    nextimage = self.acquireImage(nextscope, settle, correct_tilt=correct_tilt, corchannel=corchannel)
  File "/Users/acheng/myami/leginon/calibrationclient.py", line 120, in acquireImage
    self.correctTilt(imagedata)
  File "/Users/acheng/myami/leginon/calibrationclient.py", line 106, in correctTilt
    self.tiltcorrector.correct_tilt(imagedata)
  File "/Users/acheng/myami/leginon/tiltcorrector.py", line 160, in correct_tilt
    stagematrix = self.getStageMatrix(tem, cam, ht, mag)
  File "/Users/acheng/myami/leginon/tiltcorrector.py", line 85, in getStageMatrix
    return self.getMatrix(tem, cam, ht, mag, 'stage position')
  File "/Users/acheng/myami/leginon/tiltcorrector.py", line 82, in getMatrix
    raise RuntimeError(excstr)
RuntimeError: No stage position matrix for {name: SimTEM, hostname: anchi2.local, cs: 0.0022, pixelmax: None}, {name: SimCCDCamera, hostname: anchi2.local, cs: None, pixelmax: None}, 120000eV, 50x

After she exited Leginon and restart and use other means to adjust focus, the experiment was continued but the beam tilt was stuck at x+0.01 because the beam tilt was not returned after tilt correct failure.

r17452 catch any RuntimeError from tiltcorrector.TiltCorrector, log it and then pass. This allows acquireImage to resume its function and beam tilt return to original in measureDefocusStig. I don't think imagedata is altered in this case. Will need testing on real scope.

Please assign back to me to test, it only fails if all other calibrations needed by autoFocus exist.
