==== Using the CTF DataEditor with a Singularity Container ====
The current version of the '''CTF DataEditor tool''' runs only under CentOS Linux version 6.9. To support the MEG user community,
[mailto:holroydt@mail.nih.gov Tom Holroyd] has created a [https://singularity.lbl.gov/index.html Singularity] container for CentOS 6.9 and populated the container with the necessary libraries to run the DataEditor tool. This allows MEG users to run the DataEditor tool under the operating system (Windows, Mac OSX, Linux) of their choice.

Singularity is a
[https://en.wikipedia.org/wiki/Operating-system-level_virtualization Operating-system-level virtualization] solution where an operating system
can host another operating system in an isolated container. To run a Singularity container on your operating system, you need to install the Singularity software for your operating system. There are install packages for the major operating systems from the [https://singularity.lbl.gov/index.html Singularity website.]
