Leginon

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.
