Introduction
This structure is used to transport all information from the Testdefinition and data file to and from STREAM functions.
Overview
Field |
Description |
Header |
Structure containing the header information of the datafile, which is all information except the column data.
A description of fields in this structure can be found at http://www.geffiles.org.
Composite fields appear as structures as well.
Special attention is needed for the next fields:
- flags: indicator whether a shortname is available in the header
- bflags: same as flags but binairy
- jdx: crossreference to match a variable or text to the right shortname
|
Data |
2D-array containing the datablock (columns) of the datafile. |
Variables |
Cellarray containing the shortnames from the Testdefintion with some useful properties.
Columns:
- shortname (name of the variable)
- type of variable ('<phase>text', '<phase>var', 'column', 'system')
- sequence number of the variable within the type
- display name (quantity for var/column)
- unit(only for var/column)
- example (only for var/column; for coordinate systems, locations and calibrations it is filled with a string containing the values from the Testdefinition)
- void value (only for column)
- input editor - responsible for shortname
|
Coordinate Systems |
Cellarray containing the coordinate systems, see Coordinate Systems and Locations.
Columns:
- indicator whether a coordinate system exists in the datafile (1) or only in the Testdefinition (0)
- predecessor coordinate system
- x-translation
- y-translation
- z-translation
- x-rotation axis
- y-rotation axis
- z-rotation axis
- rotation angle
|
SensorLocations |
Cellarray containg the sensor locations, see Coordinate Systems and Locations.
Columns:
- indicator whether a location exists in the datafile (1) or only in the Testdefinition (0)
- shortname of the variable (column)
- sequence number of the variable within the type
- coordinate system in which the location is defined
- x-coordinate
- y-coordinate
- z-coordinate
|
SensorCalibrations |
Cellarray containing the sensor calibrations, see Calibrations.
Columns:
- indicator whether a calibration exists in the datafile (1) or only in the Testdefinition (0)
- shortname of the variable (column)
- sequence number of the variable within the type
- serial number
- offset
- sensitivity
- minumum of range
- maximum of range
