Hi Daniel,
Could you send me a sample input file (which can do hierarchical agglomerative based clustering)
I am finding it hard to implement it using the manual of Amber18
Thank you in advance!

Hi,
The 'leader' algorithm is not implemented in cpptraj. From my limited
knowledge of it, probably hierarchical agglomerative is the closest
one in cpptraj (although you may want to try others, like k-means).
The distance-RMSD metric is available in cpptraj, although in practice
I have not found it much different from basic RMSD with fitting.
Hope this helps,
-Dan
