Hi. I really like to keep a logfile while running relax. So I initiate relax with: relax_disp relax_1_ini.py -l logfile.txt But while the script is running, the screen does not show anything. And if i try to see the "live" log file with: tail -f logfile.txt Nothing is written. Only when relax is closed, the logfile is written out, and file is closed. Is there a way to circumvent this?
