Three

Hi day2

ToDo

• Ask about the desire to have an ESS DMSC summer school in person at LANSCE. Jean said he thinks people would be cool with it.

SciPP and PloPP

• Pronounced ‘skip’

uhhhh

• You can’t always deduce which dimension is which.

Cool Things to write about a bit more

• https://github.com/LLNL/units
• They decided to not auto convert units as it caused unexpected problems.
• The initial management of the data set is spendy, but subsequent operations/sorting/etc can be quite fast. (Explore this for imaging)
• https://scipp.github.io/plopp/examples/gallery/rectangle-selection.html
• https://mpltoolbox.readthedocs.io/en/stable/
  • “I don’t want to write GUIs, but people want to use them. So we made it really easy to make your own.”
  • Definitely tell people about the custom interfaces thing.
• https://scipp.github.io/plopp/examples/custom-interfaces.html
• You don’t have to import ‘plopp’. scipp will call plopp if needed
• They have kept plopp logic seperate, so you can use matplotlib/plopy for plotting.

Thoughts

• Obvs, SciPP can store persistent identifiers in a ’label’ for an array. super duper super cool.
• Are they doing any work with parsing LaTeX/PDFs and converting formulas into scipp functions? crazy hard and bug prone, but… ?
• Is there support for loading in ROOT and Geant4 histograms / data-sets?
• Is there talk of allowing TIFF data imports?
• Do you interact with the Fiji/ImageJ community at all?

SciPPNeutron

• Holy crap
  • Awesome

Questions

• Is there talk of combining SciPPNeutron and McStas/McStasScript?
• Once again, persistent identifiers for reduction/analysis methods, instruments, data, etc.

EPICS

• NICOS will stream the data to Kafka and into the Nexus files, and SciPP/JupyterHub/SciPPNeutron/etc will read from the Nexus-File/Kafka(? maybe, not too sure here)
