Hi @jaum20 If you are on a Mac, I found online that you can install astral with homebrew. After installing homebrew (https://brew.sh) , open a terminal and run

brew install brewsci/bio/astral

It needs to be a recent OS, however. It installed on my machine running Ventura, but not Mojave

Sorry for the delayed response.

Changing 1.6 to 1.7 in the line below should fix it:

https://github.com/smirarab/ASTRAL/blob/master/make.sh#L14

I keep this open so that I can fix it in future releases.
