Hello,

I tried to use the dpeaks algorithm for clustering with the following
command:
cluster C0 dpeaks epsilon 4 dvdfile dvdfile choosepoints auto runavg
runavg.dat deltafile delta.dat sieve 200

But keep getting the following output with error:
...
Finding closest neighbor point with higher density for each point.
 0% 10% 20% 30% 40% 50% 60% 70% 80% 90%
Internal Error: In Cluster_DPeaks::AssignClusterNum nearest neighbor is -1.
Segmentation fault (core dumped)

I will appreciate any suggestions that would fix this ...

Thanks,
Yinglong
