UrduHDD has been split into a training set and a test set.  Eigthy percent of the data has gone into the training set whereas the remaining 20 is found in the test set.  The complete sets are labeled UrduHDD80 and UrduHDD20.

Because of the mismatch in labeling the folders in the original database, there is a slight irregularity of the files in the 80/20 split.  The disk labels and block labels begin with "0" wheras the session labels begin with "1".  As a result, both the training set and the test set contain folders labeled "ADULT1UR008" and in this folder, both sets contain a "BLOCK16" folder.  The difference, however, between the sets is that in the training set, this folder contains only SES160, whereas in the test set, this folder contains SES161-SES169.


Training set (UrdHDD80):

ADULT1UR000	BLOCK00 	SES001-SES009
		BLOCK01		SES010-SES019
ADULT1UR001	BLOCK02		SES020-SES029
		BLOCK03		SES030-SES039
ADULT1UR002	BLOCK04 	SES040-SES049
		BLOCK05		SES050-SES059
ADULT1UR003	BLOCK06 	SES060-SES069
		BLOCK07		SES070-SES079
ADULT1UR004	BLOCK08 	SES080-SES089
		BLOCK09		SES090-SES099
ADULT1UR005	BLOCK10 	SES100-SES109
		BLOCK11		SES110-SES119
ADULT1UR006	BLOCK12		SES120-SES129
		BLOCK13		SES130-SES139
ADULT1UR007	BLOCK14 	SES140-SES149
		BLOCK15		SES150-SES159
ADULT1UR008	BLOCK16		SES160

Test set (UrduHDD20): 

ADULT1UR008	BLOCK16 	SES161-SES169
ADULT1UR009	BLOCK17 	SES170-SES179
		BLOCK18		SES180-SES189
ADULT1UR010	BLOCK19 	SES190-SES199
		BLOCK20		SES200


This split is also reflected in the ADULTURD00 directory containing the label files.
