LAB File - Extend File Format

The LAB file V1.1 is extended for two reasons:

• Add the measurement raster information
• Add [FUNCTION] and [GROUP] objects

The V1.1 definition is downward compatible. This ensures that tools that do not know the extensions are able to read the V1.1 files by skipping the additional information. In the experiment environment, INCA allows to write variables to a LAB file. In the variable selection dialog, LAB files can be used as a filter, to shorten up time for searching variables.

There are a number of file formats to store calibration variables. LAB files have been used for this, but some essential information is missing. With the new extended LAB file format, all necessary information for measure files are stored.

The following information is required for a complete description of measure variables: 

• [SETTINGS] Contain lab file version, multi raster separator (default separator:&).
• [RAMCELL] Contain variable name, raster (or multi raster), comment.
• [FUNCTION] Contain functions, can also includes raster and comments. The rules are the same as for the RAMCELL variables.
• [GROUPS] Contain groups, can also includes raster and comments. The rules are the same as for the RAMCELL variables.
