Other supported file formats-

Images- Composite, RGB files

Images might take upto 30 seconds to load.

VR Controls

Instructions on how to navigate through ExMicro VR can be found here (Check subsection- "Start Confocal VR, Try out test image, Manipulating image, Controlling channel visibility).

Metrics

Accessibility: The estimated time for someone to load and start visualizing data in VR

Beginner: No coding or graphics experience | < 1 hour
Intermediate: Some coding or graphics experience | < 1 hour
Advanced: Both coding and graphics experience | < 30 mins
Expert: A lot of experience with VR visualization | < 30 mins
Takeaway:
This software provides with few features to load, manipulate, controlling channel visibility and settings, a background in biology can be really helpful. Also, some of the features lag in Virtual reality but they provide with multiple features to adjust channels.
Power: The engine's power- i.e. how much once can do with this
Medium- Although, it provides features like channels such as "zoom depth", "Zoom", channel settings, etc. it still faces some lag in VR mode and application is limited to biology.

Usage: Evaluation of software's use for the following purposes

Expansion microscopy
Manipulating Image
Controlling different channels
Collaborative editing
