Use cases

Numerical (vectorial) data

Cluster vectorial (numerical) S1 dataset (data/s1.txt) to 15 clusters:

./tspg data/s1.txt --type vec -T 10  -C 15 --algo tspgclu -o tmp/s1part.txt  --cfn tmp/centroids.txt

For string data

./tspg  data/birkbeckU.txt --type txt -T 10 -C 20 --algo tspgclu --dfun lev -o tmp/birkbeckU_part.txt -H
./show_text_clusters.rb data/birkbeckU.txt tmp/birkbeckU_part.txt > tmp/text_clu.html
