display is an imagemagick program. It is used to display the images created by gnuplot. If you have xv installed, you can add -xv to the command line. Otherwise, install imagemagick

Hi all,
I am trying to use plot-twf-sess to create the motion plots as specified in the FsFast Tutorial, but I keep getting the error of "cannot find display." The command was copy-pasted from the FsFast tutorial (https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorialV5.1/FsFastPreProc_f...), and Gnuplot works on this computer (CentOS 6.8; GNOME 2.28.2) with the default terminal type set to "wxt". I've looked at the plot-twf-sess code in an attempt to troubleshoot but do not entirely understand what "display" means here where this error is generated:
which display > /dev/null if($status) then echo "ERROR: cannot find display" exit 1; endifI've searched the archives but it seems that no one has encountered this problem yet (or at least written about it), so I can't tell if I'm just missing something glaringly obvious. Thank you for your time and please let me know if any further information is needed to solve this!
Thanks again,
