Hi Shant,

These files were output by the clustering routines, so they are not that relevant to the segmentation. I have now hid them by default. If you want them back, you'll have to generate them with 3dkmeans with the new option -write_dists. 3dkmeans' -help output also contains explanations for what these files contain.

-write_dists Output text files containing various measures.
FILE.kgg.1D : Cluster assignments
FILE.dis.1D : Distance between clusters
FILE.cen.1D : Cluster centroids
FILE.info1.1D: Within cluster sum of distances
FILE.info2.1D: Maximum distance within each cluster
FILE.vcd.1D: Distance from voxel to its centroid

cheers,
z
