wcopy 
Base Table  Waveroots 
Attribute Name  wcopy 
ColumnName  wcopy 
Logical Rolename   
RoleName   
Definition  Copy number of the waveform file location. Used to distinguish between locations that contain a copy of the waveform file. The copy number should start from 1.

Base Table  Waveroots 
Attribute Name  fileroot 
ColumnName  fileroot 
Logical Rolename   
RoleName   
Definition  The top file directory of the waveform file. Subdirectories are allowed (i.e. /top_directory/subdirectory1/subdirectory2) but the top level must be included and it must be consistent with entries in SUBDIR
