  • You can collaborate on a research project or several projects within the Enclave Platform. For each project, authorized team members can use the shared collaboration space, (P: Drive), to analyze data and create output files or reports all within the Enclave Platform.

Can I import outside files or data into the Enclave Platform?

Yes. All users can upload files or data from their endpoint devices into their project-assigned workspaces in the Enclave Platform. On completion of the analyses, the project’s PI, project lead or their designees can download the output files from the Enclave Platform to their endpoint (local) devices.

Can I export files or data from Enclave Platform?

Only the project’s PI, project lead or their designees can download the files or data from the Enclave Platform to their endpoint (local) devices.

What data analytics tools are available for use in the Enclave Platform? How often are they updated?

In the Enclave Platform, there is a baseline offering of common data analytics software programs and applications such as MATLAB, R, RStudio, SAS, SPSS, STATA, and development tools (GitLab, Python, IntelliJ IDEA, Java Development Kit, Java Runtime Analysis Toolkit). The software programs and R repository packages are updated regularly. The in-platform repository (including a CRAN mirror) contains most used packages.

You can customize your environment with additional software. Please contact the Enclave Platform Support ( for assistance.

What operating system do I need to use the Enclave Platform? 

The Enclave Platform uses VMware Horizon to run and securely deliver the virtual desktops and apps.

The platform supports virtual machines running on Windows 10 or Ubuntu Linux and connects with devices running on Windows, Linux, or macOS operating systems while providing secure access for each operating system and streamlined desktop management.

What are the browsers requirements for the Enclave Platform?

What will happen to my workspace and data at the end of the project or if I leave the project?

On completion of your project, all data files pertaining to the specific project in the individual user-level folders and group-level  folder will be retained indefinitely.

Storing Files or Data in the Enclave Platform

In the Enclave Platform, each user has a dedicated workspace and only they can access it. Each Enclave Virtual Desktop computer has a local computer drive, the C: Drive, and a personal network drive, the H: (Home) drive. The intended use is for storing only project-related files at the individual user-level.

The C: drive is best utilized for temporary storage of files or data that you are working on and should not be used for long term storage.

Use the H: Drive to store files that you wish to back up and/or access from different computers or devices if you are the only person needing access to the files or data.

Whenever other members of the project need access to shared files or data, the use of the P: (Project) drive is recommended. The intended use is for storing shared project-related files.

  • The P: Drive belongs to the team and not an individual member of the team i.e., the P: Drive is a collaboration space where project members can readily store, share, and analyze data.
  • The project’s PI has complete control over access to the P: Drive at the folder-level via the Partners PAS system and oversight of shared data or files by their team.

How do I access the C: drive, H: drive, or P: Drive?

The C: drive, H: drive, and P: drive are automatically mapped and should be visible on your Enclave Virtual Desktop computer and when saving or accessing files from within an application. Remember: You should be connected to the MGB VPN to access your workspace in the Enclave Platform.

What are the advantages of storing my files on the H: drive or P: Drive?

The H: and P: drives are network drives that are backed up daily. The backup system provides a safeguard against accidental loss of data and offers an added level of protection against malware and other security risks.

What kind of data is hosted in the Enclave Platform? 

Microsoft SQL databases

  • COVID-19 Data Mart
  • COVID-19 Vaccine Registry
  • COVID-19 Vaccine Self-Reported Symptoms Database
  • SQL scratch pad (project-specific databases)

Other Data Sources

  • COVID-19 Detailed Data Files (CSV Files)
  • ECG Data Files (Muse Files)

Collaborating within the Enclave Platform 

How many people can use the Enclave Platform concurrently? How much workspace does each user have?

The Enclave Platform accommodates several users at the same time. A single security server can support a maximum of 2000 concurrent sessions or connections. The Analytics Enclave Team will work with you to determine how many workspaces are necessary for your research project.

Each user has access to a personal workspace and a data storage area. A shared project space is also available if multiple researchers are collaborating on the same project. 

Each user’s personal workspace has a C: Drive and H: Drive with ~ 70 GB of combined available storage. However, the configuration can be modified to suit your data analytics needs.

Each project’s shared workspace has ~ 120 GB of storage. Additional storage can be provisioned upon request.

Can I use the Enclave Platform to collaborate on a project with another researcher within MGB or at another institution?

Yes. Collaborating on a research project is easy to do in the Enclave Platform environment. The project members can use the shared project-specific workspace, P: Drive, to analyze data and generate research outputs. Note that each user will access the shared data, create results reports, and other research outputs via their dedicated virtual desktop computer and with their MGB login credentials.
