The /PhaseInfo Group

Phase Information is stored in the /PhaseInfo group and is linked with to the /LabDCT/Data/PhaseId data set. The number encoded in the group name, e.g. /PhaseInfo/Phase01 refers to all voxels with PhaseId==1.

Phase Information, XX refers to the PhaseId (e.g., 01, 02 etc.)

Dataset	Data Type	Dimension	Unit
/PhaseInfo/PhaseXX/FileName	string	varlen
/PhaseInfo/PhaseXX/Name	string	varlen
/PhaseInfo/PhaseXX/SpaceGroup	int32	1
/PhaseInfo/PhaseXX/UnitCell	double	6	Å,°
/PhaseInfo/PhaseXX/UniversalHermannMauguin	string	varlen
*/PhaseInfo/PhaseXX/Color	int32	1	RBGA
*/PhaseInfo/PhaseXX/HKL	string	varlen

IPFColorbar

To be able to interprete the RGB Color Coding the result file may contain the color key within the /PhaseInfo/PhaseXX group.

The full data set name expands to, e.g., /PhaseInfo/Phase01/IPFColorbar/RGB.

Optional IPF color key within the /PhaseInfo/PhaseXX group

Dataset	Data Type	Dimension	Unit
*/IPFColorbar/Coords	float	X x Y x 2
*/IPFColorbar/RGB	float / uint8	X x Y x 3	RGB
*/IPFColorbar/AnnotationPosition	float	3 x N
*/IPFColorbar/AnnotationOrientation	float	N
*/IPFColorbar/AnnotationText	string	N

Additional Datasets

Acquisition Parameters

The acquisition meta data may sit directly int the /LabDCT or /AbsorptionCT group and contains basic information.

The full data set name expands to, e.g., /LabDCT/Filter.

Additional acquisition parameters in the /LabDCT or /AbsorptionCT group

Dataset	Data Type	Dimension	Unit
*/Filter	string	varlen
*/NumberOfProjections	int32	1
*/Objective	string	varlen
*/SampleToDetectorDistance	double	1	mm
*/SourceToSampleDistance	double	1	mm
*/Voltage	double	1	kV

Labels

A Volume may contain label information in the /LabDCT or /AbsorptionCT group.

• /LabDCT: refers to the /LabDCT/Data/Mask data set

• /AbsorptionCT: refers to the optional */AbsorptionCT/Mask data set.

The full data set name expands to, e.g., /LabDCT/Labels/Names.

Label Information

Dataset	Data Type	Dimension	Unit
*/Labels/Colors	int32	L	RGBA
*/Labels/Labels	uint8	L
*/Labels/Names	string	L x varlen
