That line reads:

        Rectangle r = ip.getRoi();

suggesting to me that maybe there was a 0-slice image.

Your macro is very long and assumes certain files and directories to be
present. Under normal circumstances, I would try to find half an hour to
reduce it to a minimal example, but today I simply do not have time.

Would you mind reducing the macro to the bare minimum displaying the
error? I would then finagle a gap into my schedule to debug and fix it.

Ciao,
Johannes
