Mapinfo Pro Advanced and issue where the Contour Process button is disabled

Product Feature: Contour

Product Affected: MapInfo Pro Advanced™
 

Issue

User running MapInfo Pro Advanced is trying to create a contour table from a .mrr file but the
Process button is not available.

Cause

 The .mrr file in question had only a single value of "1" at all cells, verified with the Statistic tool.
Contouring requires a range of data to create contour breaks, therefore the process button was not available.

Resolution

UPDATED: June 9, 2020
A better alternative would be to use the Polygonise" tool, as it can create boundary lines along edges of data value cells.
