06.1.3.2 Dumping an IDS node
Getting a subset of an IDS enables reading only a node (and its descendants if the node is a structure), making the GET operation much faster. To retrieve only requested node one should call the script idsdumppath
.
Code Block |
---|
idsdumppath
Usage: idsdumppath <USER> <TOKAMAK> <VERSION> <SHOT> <RUN> <IDS> <DATA_PATH> |
Path syntax:
- The path to requested node(s) is separated by slashes (“/path/to/node(s)”).
- Nodes representing arrays must contain indexes (“/path/to/array(idx)/field”) or “Fortran style” indices (“path/to/array(x:y)/field”)
- Limitation: In case of nested arrays, it is not allowed to specify set of indices for AoS ancestors. Only given values of AoS ancestors indices are handled: (e.g. “field/with/ancestorAoS(x:y)/field/AoS(n :m)” is not managed)
Data query examples:
- “flux_loop(1)/flux/data(1:5)”
- “bpol_probe(2:3)/field/data”
- “loop(:)/current”
- “time(4:-1)”
- “profiles_1d(2)/grid/rho_tor_norm(2:4)”
