I've been reaching the limits of the clustering program, as I am trying to cluster many years of contiguous trajectories. I have hit some sort of limit to the CLUSTER file size, and was wondering about the cause.
Thus far, I have been successful in clustering 41 years of daily trajectories (120 ...

Re: Back-trajectory calculations taking significant time
If you are having trouble with computation time, and you're using a standard hysplit install (i.e., not parallel), the most likely culprit is your processor's single-core performance. Hysplit will only use a single CPU core, and there isn't much that can be done to speed it up for a set hardware ...

Re: Error while generating Mean cluster in Trajectory Cluster analysis
Hey mate, just posting as I was getting an identical error and I managed to solve it. I had been trying to plot the cluster means for a set of endpoints that contained different combinations of output variables (i.e. pressure, theta, air temp, rainfall, etc.). The clusters were not running, so I ...
