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 GEF keyword (e.g. setuptext, projectid) is available in the header
- bflags: same as flags but binairybinary. In addition for indexed keywords the presence is shown on element level. The number of parts within a keyword is expressed in a binary value (1 = 1 value; 3 = 2 values; 7 = 3 values etc).
- jdx: crossreference to match a variable or text to the right shortname
See an example below
|
Data | 2D-array containing the datablock (columns) of the datafile. |
Variables | Cellarray containing the shortnames from the Testdefintion with some useful properties in columns, see Create a Testdefinition. 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)
- name of the coordinate system
- predecessor coordinate system
- x-
coordinate- translation
- y-
coordinate- translation
- z-
coordinate- translation
- x-rotation axis
- y-rotation axis
- z-rotation axis
- rotation angle
|
SensorLocations | Cellarray containg the sensor locations, see Coordinate Systems and Locations | | | Calibrations | | . 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
- target quantity number
- minumum of range
- maximum of range
- calibration date

Piece of GEF file:
#TESTID= Test_1
#PROJECTID= CO, 1234567, 890
#SETUPTEXT= 1, Our best customer, Name
#SETUPTEXT= 1500, none;0;0;0;1;1;1;0;, StartLab
#SETUPTEXT= 1499, StartLab;20;1;0.7;0;0;0;0;, StartLab TableInLab
Header structure information:
- Header.testid (not indexed; not composite): field containing string
Header.projectid (not indexed; composite): 1x1 struct containing fields 'type', 'number' and 'subproject'
Header.setuptext (indexed; composite): 1x3 struct containing fields 'idx', text' and 'explanation'; idx is filled with 1, 1500 and 1499 (note the order) - Header.flags.testid = 1
Header.flags.projectid = 1
Header.flags.setuptext = 1 - Header.bflags.testid = 1 (1 part)
Header.bflags.projectid = 7 (3 parts)
Header.bflags.setuptext(1) = 7
Header.bflags.setuptext(1499) = 7
Header.bflags.setuptext(1500) = 7 - Header.jdx.setuptext(1) = 1;
Header.jdx.setuptext(1499) = 3;
Header.jdx.setuptext(1500) = 2;
