Macro Processing - a problem with multiple BEGIN loops not processing from the top of the well has been resolved.
TerraStation Version 7.418 - 22 June, 2016
Borehole Imaging - a new image heterogeneity index computation uses percentiles within the display range. This should be used when in Static image mode, equal increments. Accuracy improves with a larger number of bins.
Clarity - a new data analysis module has been added to the software. This module is available to all TerraStation users. An upcoming newsletter details how to use this tool.
Preferences - a user preference controlling Clarity window management has been added to the Miscellaneous section.
Curve Splicing - the run ID is now displayed with the curve header information. Splicing operations can reference the run ID to allow all curves from the specified runs to be spliced in one operation.
Map Export - a problem with column alignment when exporting locations for all selected tops has been resolved.

This is intended for use as a diagnostic for tool eccentering.
