CyPRG datasets published in 2001 are organized differently than datasets published previously.  In the reorganized database, most of the criteria are identical.  However, redundant criteria have been deleted, and all fields in the database have been renumbered.

The following table gives the pre- and post-2001 field numbers, which can be used to reorganize their own copies so they will be compatible with datasets released in 2001 and later.

This information will be useful only to those researchers who have used CyPRG data before 2001.
