Restrictions

The restrictions listed here are issues with the scripting interface itself. temscript only provides Python bindings to this scripting interface, thus these issues also occur using temscript. As there is no public list of known issues with the scripting interfaces by FEI or Thermo Fisher Scientific themself, known issues are listed here for the user’s reference.

  • Changing the projection mode from IMAGING to DIFFRACTION and back again changes the magnification in imaging mode (Titan 1.1).

  • Projection.Magnification does not return the actual magnification, but always 0.0 (Titan 1.1)

  • Setting the binning value for a CCD camera, changes the exposure time (Titan 1.1 with Gatan US1000 camera).

  • Acquisition with changed exposure time with a CCD camera, are not always done with the new exposure time.

  • Illumination.IntensityLimitEnabled raises exception when queried (Titan 1.1).

  • GoTo() fails if movement is performed along multiple axes with speed keyword specified (internally the GoToWithSpeed method if the COM interface fails for multiple axes, Titan 1.1)

  • Querying the attributes STEMAcqParams.DwellTime, Illumination.StemMagnification, and Illumination.StemRotation fails, if STEM is not available (Titan 1.1)

  • If during a specimen holder exchange no holder is selected (yet), querying Stage.Holder fails (Titan 1.1).
