Hi,

I am running ptraj cluserting (average linkage) for MD trajectories (20 ns) of a
protein-ligand complex and
it has been running for more than 24 hours now, still not completed and the
present output at the
terminal is
.....................................................................
The first pass through the trajectory is complete.
  Calculating the PairwiseDistances
  Writing Pairwise Distances to file "PairwiseDistances".
  Clustering using the average linkage algorithm.

I am sure people have run such cluster analysis for even longer trajectories.
Can someone
suggest me how to approach this problem to make it quicker?
will it be OK? if I split the trajectories into a few groups and do analysis
within each group?

thanks in advance,

Senthil Natesan
