Use the U matrix for clustering.
Note that you are replicating what the spectral clustering already does.

many people also use PCA options workflow with SSVD and then try clusterize
the output U*Sigma which is dimensionally reduced representation of
original row-wise dataset. To enable PCA and U*Sigma output, use
ssvd -pca true -us true -u false -v false -k=... -q=1 ...
-q=1 recommended for accuracy.
Thanks
