Hi, Jim-

I think 2017 was back when AFNI was written in cuneiform or Linear B... That is, it is a very old version (just past its 3rd birthday, in fact).

My *guess* is that your current node has Python 3 on it, and that version of afni_system_check.py (as well as other Python programs in AFNI) might won't be happy with it; your other node might have Python 2 (though, I don't know what version of AFNI with Ubuntu you have there). To check local python version, try "python -V".

*Regardless*, I think on all your nodes, you should run:

@update.afni.binaries -d

so you have current AFNI; we can't reverse engineer solutions for extremely old versions of programs. It will just replace whatever package you have (Ubuntu, xorg, etc.) with the most recent version of the same package, so it won't swap you over to another type. Verify that your node has the most recent version running with:

afni -ver

Then run:

afni_system_check.py -check_all

... and we can get back to discussing the R stuff that you initially asked about.
