Hyperspectral image (2D+Spectral dimension) was loaded.
Entire spectrum for each pixel was considered as a "Spectrum Curve".

Original image and a representative spectrum for the specified pixel

Entire population of pixels was clustered (using fixed number of cluster=7) so that all the Curves within cluster are similar to each other and different between clusters.

labeled map of clusters (7 clusters = 7 colors)

Each cluster corresponds to a distinct spectrum.  7 clusters were chosen because at 8 clusters the corresponding spectrum curves became less distinct.

RoiStat4D dialog box:  fixed the "inifinite loop while editing the value" issue.

Fixed the defect when on FVX exit the Working directory was cleaned out instead of App\Temp directory.
