Hello!

I am going through the HYSPLIT installation process on Ubuntu (Hysplit version 5.2.3). I can get through the installation process alright but cannot open the GUI through the command line using the ./hysplit.tcl command. I think the main issue is that my tcl is not being installed properly and/or Hysplit cannot find where tcl is installed.

When I try to install tcl (through ActiveState), I am unable to install it in the suggested directory (in my /opt directory) because I get an error saying "You are trying to install ActiveTcl inside of the directory containing the distributed files."

I was also wondering if it would be a better idea to change the path to tcl in the /guicode directory in the Hysplit folder but am unsure what line in the relevant text file I would have to change.

If anyone has any ideas for how I can move forward, I would really appreciate it!

Thank you!

To check if tcl is correctly installed on your Ubuntu computer, open a terminal and run "which wish." It should print where the wish program is located, as shown below: If "wish" is unavailable on your computer, you will need to have it installed by running something like "sudo apt-get install tk". The exact command may depend on your Ubuntu version so you might want to do some Internet search.

Once the availability of "wish" is verified, follow Step 4 at https://www.ready.noaa.gov/documents/Tu ... _unix.html to create a soft link in your hysplit/working directory and run ./hysplit.tcl inside the working directory.
