Metrics

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

Beginner: No coding or graphics experience | < 2 hour
Intermediate: Some coding or graphics experience | < 1 hour
Advanced: Both coding and graphics experience | < 30mins
Expert: A lot of experience with VR visualization | < 30mins
Takeaway:
This software provides with multiple features to view your molecular and EM structure in VR, a background in chemistry and biology can come really handy to understand various features and its implementations. Some of the features does face some lag in Virtual reality but it does provide with multiple features to easily understand the data.
Power: The engine's power- i.e. how much once can do with this
Medium- Although, it provides multiple features- from viewing molecular structures, density maps, medical Images, etc. , it still faces some lag in VR mode while using few features and the usage of the application is limited to biology and chemistry.

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

Display and Analysis of Structures
Density Maps
Medical Image
Graphics
Viewing of Molecular Structure
