The Data Filters controls are largely self-explanatory but require some commentary (Fig. 2.2-32).
- Data filters are applied to the data from all cores for a specified data type. For a more specific filtering of known intervals with severe core disturbance, etc., you have the option to apply a file with those intervals specified in the Correlator Downloader application, at the time of data download.
- At this time, data culling can only be specified for top of cores (to remove data from “exotic” material washed down from higher up in the hole). A future version will include culling from core bottoms (“exotic” material “sucked in” when the piston core was removed) and culling from section ends (“edge effect”).
- Some odd behavior has been observed when deleting a cull filter under certain circumstances, and this has not yet been repaired (no user pressure). An easy workaround is to re-load the data.
Figure 2.2-32. Three data filtering options on the Data Filter tab: Decimate, Gaussian Smoothing, and Cull. Shown is a 9-point Gaussian filter applied to the magnetic susceptibility data whereby both original and smoothed (white trace overlay) are plotted. The filters can be edited or deleted.

This tab offers numerous display options that applying apply to core shifting and splicing functions (Fig. 2.2-3a). Two new features include the ability to change the display order of the data types, including not showing them (Fig. 2.2-3b) and the ability not to display the data for selected holes (Fig. 2.2-3c). Data ranges can be set numerically for each data type (Fig. 2.2-3d) and visually be adjusting track widths. The color panel is updated so you can adjust the scheme to your liking. Additional check boxes were added to toggle on or off the display of lines, arrows and labels. These options should all be self-explanatory. Load some data, shift some cores, make some splices, and then simply explore the options be clicking around - nothing your selections will not affect the data.
