Hi. I'm new in HYSPLIT.

I'm trying to cluster my five year long wind data (.gbl). I clustered my data before with TrajStat. But TrajStat is not doing iteration so it's not giving a specific cluster number. I have to use trial-and-error method in TrajStat and I think it's not completely true.

I'm using this tutorial for understand how can i cluster my data with HYSPLIT

but it's just showing for 1 month. How can i use this cluster analysis with 5 year long data. How can i load my all data in an lumb.

All the trajectories in the file INFILE will be clustered. As you say, the example is for one month. You need to create an INFILE with all your trajectories. Due to possible memory issues, start small, say one trajectory a day for year, increase it to two years, etc. For information about memory, see viewtopic.php?f=12&t=516&p=1781&hilit=c ... mory#p1781

TSV figure has been added in clustering function of TrajStat Java plugin from 1.4.3 version. So you can get a specified cluster number with the TSV figure using neweast MeteoInfo Java and TrajStat plugin version.

Thank you for your answer. This is a good solution.
