Clustering issue
See original GitHub issueHi,
Please note that I am using the following code for clustering, but I got this error “Number of clustered events: 0/119 (0.000000%), Impossible to calculate silhouette score. Only 1 cluster group identified”
suppa.py clusterEvents --dpsi cold_cond.dpsi --psivec cold_cond.psivec --sig-threshold 0.05 --eps 0.05 --min-pts 20 --groups 1-4,5-8 -o salt
I don’t know what that means!! Please help, Thanks in advance
Nour

Dear Nour,
In the wiki page we give some ideas to visualize results https://github.com/comprna/SUPPA/wiki/SUPPA2-tutorial
In the SUPPA2 paper, we simply plot PSI values along the different time points.
SUPPA2 calculation of events also gives the events in GTF format that you can either use in UCSC or with a different tool for visualisation.
I hope this helps

Dear Nour,
thanks for your message. This is not really an error. It simply states that only no clusters could be formed using those parameters. Accordingly, the silhouette score cannot be calculated.
Please try changing the parameters for the clustering, like --eps, –min-pts,… to reduce the thresholds to form clusters.
I hope this helps
Best
