Heya,
Yes afni launches just fine, and everything looks absolutely normal, however the error message keeps repeating in the background on the command line as long as the viewer is open.
The only thing I did recently was move my data off my local machine onto a server and back again.... so perhaps something funny happened then? Also, I changed my OS from Red Hat to Fedora, and now finally to Ubuntu (which is the final change for sure, lol!) Maybe some of these changes could have affected the integrity of the files?
