Hi,
I have been using AFNI on my Desktop (Running Ubuntu 18.04) and Virtual Machine (also running Ubuntu 18.04) for a long time. Recently I installed AFNI on my Laptop (running Ubuntu 18.04 as well). I use the same dataset and same script on all the machines but my laptop sometimes fails to read the CSFtimeseries.1D. It happens randomly and happens for the same data each time. But it runs perfectly on other machines without any problem. I tried the "afni_system_check.py -check_all" and it shows no problem. Everything is the same on all the machines. I really can't figure out what seems to be the problem.
