Why isn't my research data directory in '/nfs'?

It is, or at least will be as soon as you need it! Any research data directory you have access to will be mounted to the filesystem at “/nfs'' when you access it. If you have not touched any of the files in there for a while, it may have unmounted and appear to be missing. So if you don’t see your “*-data” folder under “/nfs”, just navigate directly to the folder and it will instantly mount. For example, if your research data directory is “cooltrees-data”, then enter the full path as “/nfs/cooltrees-data” in the file browser or from the command line.
