In order to benefit from UAL layer, scientific data must be stored in MDSPlus database. Before you will be able to use it, you have to create database's structure. This is fairly simple. All you have to do is to execute following commands:
source $ITMSCRIPTDIR/ITMv2 test kepler > /dev/null $ITMSCRIPTDIR/create_user_itm_dir test 4.10bimasdb <machine_name>
At this point, you can check your public directory and browse through the database structure.
cd $HOME/public/itmdbimasdb/itm_trees
Explanation of the tree structure:
| location | description | ||||
|---|---|---|---|---|---|
| $HOME/public/itmdb | /itm_trees/$TOKAMAKNAME/<machine_name>/<data_version>/<MDSPlus_tree_number>/ids_<shot><run>.* example: | ~owsiak~/public/imasdb/test/3/0/ids_120001.* | |||
| <machine_name> example: test/itmdb/itm_trees/test) | defines the equipment used for acquiring the results; "test" - is most commonly used for artificial, test data | ||||
| $HOME/public/itmdb/itm_trees/$TOKAMAKNAME/$DATAVERSION/mdsplus example: ~owsiak/public/itmdb/itm_trees/test/4.10b/mdsplus | contains experimental data for given UAL version | ||||
| <data_version> example: 3 | Major Data Dictionary version | ||||
| <MDSPlus_tree_number> example: $HOME/public/itmdb/itm_trees/$TOKAMAKNAME/$DATAVERSION/$MDSPLUS_TREE_BASE_$NUMBER/ example: ~/public/itmdb/itm_trees/test/4.10b/mdsplus/0 | Contains all the shot and runs for given data tree | $HOME/public/itmdb/itm_trees/$TOKAMAKNAME/$DATAVERSION/mdsplus/$MDSPLUS_TREE_BASE_$NUMBER/ids_$SHOT example: ~/public/itmdb/itm_trees/test/4.10b/mdsplus/ids_120001. | |||
| Run number | Run number is represented by last four digits in database file ids_SSSSRRRR.* | ||||
| Shot number | Shot number is represented by first digits in database file ids_SSSSRRRR.*; there is no limit for number of digits usedContains data for given shot | ||||
ids_####.datafile, ids_####.tree, ids_####.characteristics | Contain Contains data for givet given shot/run | ||||
