Error in Cluster Analysis - Cannot read tdump files
Posted: December 17th, 2018, 3:18 am
I am trying to run cluster analysis on a long stream of back trajectories. I have 5, 7, and 10 day lengths and at multiple heights. I have tried running the cluster analysis several times with my files and can't seem to get them to read. I have tried using a few different sets of trajectory files. The groups all start at the same height and within the same year. No matter which ones I use, I receive one of two error messages.
If the "Hours to cluster" is less than 5, I receive this error:
Model started ... it is slower at the beginning
Started Cluster (Version: April 2015)
Number of trajectories in INFILE: 31
clusread - should not be here; this traj has fewer endpts than needed
If I use 5 or more hours, I receive this error message.
Model started ... it is slower at the beginning
Started Cluster (Version: April 2015)
Number of trajectories in INFILE: 31
NOTICE - No trajectories to cluster. Check trajectory duration
in the files in INFILE and/or the Hours to cluster
I have checked the tdump files and they are complete to at least -120 hours. I have placed the files in the endpts file. I can create the INFILE, but not the clusters. When I copied my trajectory data onto the example files, they work fine. Normally this wouldn't be a problem, but I have a few hundred clusters that need completed.
The only thing I can think of that might be causing problems is the header on my files is larger than the header on the example files. Is there a limit to the header length that can be used with the cluster analysis?
