Hi Jianyin,
The silhouette.pl script froze my computer with 4GB ram when I ran it on a
570MB PairwiseDistances and 12140 frames in ClusterMerging.txt. I wonder if
there's a way to estimate the memory usage and run time based on the input
filesize? Do you have any silhouette programs that are binaries compiled in
C or Fortran?
Thanks,
Dong
