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 .
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 AoS, 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)” “ids_properties” occurrence is a number indicating the occurrence of the target IDS in the Data Entry
