Default private databases are MDSplus. Before using MDSplus tools to access them you must define an environment variable:
setenv euitm_path $HOME/public/itmdb/itm_trees/test/4.08a/mdsplus/0Now you can use mdstcl, jTraverser and jScope to access the data.
To access MDSplus data using jTraverser, select file > open, then Tree: euitm, Shot: <the number following euitm_ in the database file name>.
