No trajectories to cluster

Post by nottinghamhj »

I have done the cluster using the example which went through pretty smoothly. Afterwards when I tried to run my own tdump files in the "endpoints" folder, "Make Infile" seemed ok but after click "Run cluster", the following error kept coming up:

Model started... it is slower at the beginning
Number of trajectories in INFILE: 70
NOTICE - No trajectoreis to cluster. Check trajectory duration in the files in INFILE and/or the Hours to cluster

All the tdump files are for backward trajectories of 96 hours.

How to overcome this issue?

Many thanks, Jun

Open the INFILE in Notepad and verify the files exist. Make sure your "hours to cluster" are less than or equal to 96 (and >0). See if in the cluster 'working' directory there is a file "CLUSTERno". That would list the trajectories not being clustered and presumably would be all of yours. Are your endpoints at the traditional 1-hour interval? You have "Trajectory skip" at the default 1?
