MolCollabo is software that enables the 3D display of biomolecules such as proteins and nucleic acids on a head-mounted display, allowing for a virtual reality (VR) experience. By connecting VR spaces through network communication, the displayed molecular structures can be shared and viewed by multiple people, including those in remote locations. This facilitates communication with researchers engaged in structural analysis and molecular simulations. Additionally, the software allows for configuration and operation solely through a PC screen.
