Open Cull Table:

This feature allows the user to apply a previously-saved CULL TABLE (Sitexxxx.cull) to any dataset from that site. The CULL TABLE contains data values which were removed from the input datasets and the reason for their removal. The file is stored/read in a binary format. A CULL TABLE must first be saved before it can be opened.

A reason for saving the CULL TABLE is that it can be applied in a subsequent SPLICER session to identify core voids and other coring problems within another dataset from the same drillsite. For example, one can initially cull all GRAPE density values less than ~1.2 to identify and remove data from core void intervals. The resulting CULL TABLE can then be used to identify and remove core voids from other volume-dependent MST measurements such as magnetic susceptibility and gamma ray activity.

When the CULL DATA... button is activated in the READ DATA... window, the program applies the selected data culling (removal) criteria on the selected data files. Data which are not culled are then passed to the SMOOTH... and DECIMATE... routines, if selected, and then are plotted in the left-hand composite panel of the main Slicer window.

CULL TABLE files are identified by the *.cull suffix.(e.g. Sitexxxx.cull).
