Description
Type
Data Process.
Behaviour
It executes an operation between two datacubes with the same fragmentation structure and returns a new datacube as result of the specified operation applied element by element.
Parameters
- cube: name of the first operand datacube. The name must be in PID format.
- cube2: name of the second operand datacube. The name must be in PID format.
- operation: type of inter-cube operation among these (default is sub):
- sum: sums correspondent elements one by one
- sub: subtracts the elements of the second operand from the first operand one by one (default)
- mul: multiplies correspondent elements one by one
- div: divides the elements of the first operand by the elements of the second operand one by one
- abs: computes the modulus of corresponding elements one by one
- arg: computes the phase of corresponding elements one by one
- corr: computes the Pearson correlation coefficient row by row
- mask: takes all elements of cube corresponding to 1s in cube2, remaining elements are set to 0 (int, byte, short or long) or NaN (float or double)
- max: return the maximum value between the corresponding elements one by one
- min: return the minimum value between the corresponding elements one by one
- missingvalue: value to be considered as missing value; by default it is NAN (for float and double).
- measure: name of the new measure resulting from the specified operation.
- schedule: scheduling algorithm. The only possible value is 0, for a static linear block distribution of resources.
- container: name of the container to be used to store the output cube; by default, it is the container of the first cube.
- description: additional description to be associated with the output cube.
System parameters
- exec_mode: operator execution mode. Possible values are async (default) for asynchronous mode, sync for synchronous mode with json-compliant output.
- ncores: number of parallel processes to be used (min. 1).
- sessionid: session identifier used server-side to manage sessions and jobs. Usually, users don’t need to use/modify it, except when it is necessary to create a new session or switch to another one.
- objkey_filter: filter on the output of the operator written to file (default=all => no filter, none => no output, intercube => shows operator’s output PID as text).
Examples
Sum the datacubes identified by the PIDs “URL/1/1” and “URL/1/2”:
[OPH_TERM] >> oph_intercube cube=URL/1/1;cube2=URL/1/2;operation=sum;measure=new_pressure;
