Linux Support and New Features

This release adds the following:

• Real-time dF/F display option for Miniscope video stream
• Add initial support for new open-source behavior cameras (Minicams) we have been developing.
• ROI selection for behavioral cameras. This ROI can be adjusted in real time through the behavior camera video window or can be configured in the User Config file.
• New head orientation real-time display showing if orientation data is not stable. The User Config now also includes the option to filter out unstable data.
• Major improvement to external triggering thanks to suggestions from @dysonsphere-startmail. These include:
  • Excitation LED toggling on and off based on external trigger state.
  • The ability to start and stop recording even when external triggering is enabled.
• Added a more flexible structure for defining the data directory in the User Config file. This comes thanks to a suggestion from @dysonsphere-startmail.
  • In "directoryStructure" you can now define your own name types and no longer be limited to the few initial name types supported by previous versions. Within the User Config File you will also then need to set a string value for these new name types. The save metaData.json file created during recording will also save this new name/value pairs.
  • For example, if you add "animalColor" to the "directoryStructure" then you will want to also add "animalColor": "Brownish-White" into the User Config file right under "directoryStructure".
• Linux support thanks to contributions from @ximion and @phildong.

We will be updating the V4 Miniscope Wiki with more information on the new features and data structures within the User Config files but for now you can also look at the included example userConfig files to see how to handle defining behavior camera ROIs and how to enable head orientation data filtering.
