Alternately, if the error is high and the plot shows obviously erroneous data in one region (spikes/noise), there may be a
problem with the analysis in that region; check the images and AOI boundaries. If necessary, reduce the analysis area, or
use threshold settings to eliminate the bad data.
If no points can be analyzed, an error will be shown. The most common reason for this condition would be that the
software could not determine an automatic initial guess. In this case, check the previous section of this guide, Initial
Guesses.
