No, it isn't.

This means nothing to me. Exactly where is this code located? Where can
I find the loadMultiTiff() method? Does it still work if you have
separate images for the two channels?
For the code to be useful I need something I can put in and compile
without having to redo things that you probably already have done.
A diff would probably work.

It would be nice to have an image and some raw data with it. It doesn't
have to be a complete file. Remove all headers (except those needed for
the spot image creation) if you like. We have a locked repository for
test data that we aren't allowed to share.

It seems like you are right. All programs I have tried to use also fail
to open the zip file. I know that it has worked before so something is
probably broken, except that Java seems to not have the same problems.
