Dear ImageJ List Members,
The system admin for the Mac cluster I'm using installed headless
ImageJ for me on the cluster. We tried running a simple macro,
Arrays.txt. He could only get it to work if logged in as root.
Otherwise he gets the errors listed below.
Any thoughts?
Thanks,
Brian

Hi Brian,
I have downloaded headless.jar on /Volumes/xserveraid/Applications/
ImageJ/. I tried to run one of the simple macros in batch mode as an
user and a root.
As an user, there are still permission problem, but as a root, it ran
through. I give you this result for your information.
[wlee ImageJ]$ java -classpath headless-ij.jar:ij.jar
ij.ImageJ -batch Arrays.txt
kCGErrorRangeCheck : Window Server communications from outside of
session allowed for root and console user only
