| Tried to prepare a new configuration phase via PsychImaging('PrepareConfiguration'), but did not finalize the previous phase yet. | |
| You must call the PsychImaging('OpenWindow', ...); command at least once to open an onscreen | |
| window according to the provided settings, before you can specify settings for additional onscreen windows. | |
| The most likely reason you see this error message is because your script aborted with some error | |
| before it managed to open the onscreen window. In that case it is best practice to execute a 'clear all' | |
| command at the Matlab/Octave prompt before you restart your script. | |
| I will restart configuration now and forget the previously made PsychImaging('AddTask', ...); settings. | |

| INFO: PTB's Screen('Flip', 10) command seems to have missed the requested stimulus presentation deadline | |
| INFO: a total of 3 times out of a total of 604 flips during this session. | |
| INFO: This number is fairly accurate (and indicative of real timing problems in your own code or your system) | |
| INFO: if you provided requested stimulus onset times with the 'when' argument of Screen('Flip', window [, when]); | |
| INFO: If you called Screen('Flip', window); without the 'when' argument, this count is more of a ''mild'' indicator | |
| INFO: of timing behaviour than a hard reliable measurement. Large numbers may indicate problems and should at least | |
| INFO: deserve your closer attention. Cfe. 'help SyncTrouble', the FAQ section at www.psychtoolbox.org and the | |
| INFO: examples in the PDF presentation in PsychDocumentation/Psychtoolbox3-Slides.pdf for more info and timing tips. | |
| PTB missed 3 out of 600 stimulus presentation deadlines. | |
| One missed deadline is ok and an artifact of the measurement. | |
| PTB completed 0 stimulus presentations before the requested target time. | |

datapixxStereoDemo.m, in/debugging/runs fine on OSX, as long as you are careful with making sure the glasses are seeking the emitter.crossedBaselineRT.min the private/occlusion/repo also runs fine on OSX.
