I have been try to carry out on a clustering run on backTraj data from 2009 to 2019 (120 hrs of backtraj at a time interval of 6 hrs). Hysplit is finishing the clustering, displays the TSV, assigns the trajectories, but displays the error above when I press Display means. It has started to do this a...

In the previous versions of Hysplit it was possible to download Reanalysis datasets (using the GUI) from the Meteorology tab >>> ARL Data FTP >>> Reanalysis (4th option). I have now upgraded to the April 2020 version (on Mac) and this option is no longer available the only options in the Meteorology...

Ok, so if I want to find out the number of trajectories in cluster N in January for example, all i have to do is convert this file to .csv and look for the required info?

How I can extract the trajectories apportioned to each of the clusters? I need to perform a cluster analysis however I need the number of trajectories assigned to each month to, so somehow I have to extract all the data for the trajectory together with the cluster number.

Thanks

In research articles yes, not using the clustering function in Hysplit though. I am using a 2008 Sony vaio with 4 GB Ram. How much memory would be enough to carry out this type of calculation?

I have tried this too, the calculation starts, It says Number of trajectories in INFILE: Pass 1 out of .... But then it stays like this for a very long time, to the extent that I left the pc on, checked after 4 hours and nothing changed, i left the pc on overnight, and I found that it had shut down!...

I am performing a cluster analysis of back-trajectories from 2008 to 2013 (length 120hr at 6hr intervals) for 6 years and I keep getting the following error: "Error: can not find channel named "0"". I do not get the error when I run the cluster analysis for 2008 to 2012 or from 2009 to 2013 or for a...
