How do I workaround a “Noisemap grid file could not be opened” error?
NMPlot is a DOS application with an 8-character filename/directory limit. If your TNM run name is greater than 8 characters or is embedded within many subdirectories or has long subdirectory names, then NMPlot may display this error. Shorten your run name or move your run out to the main C: directory to run contours.
