I'll need a little more help to figure this out.  Run isis as:

unix%> isis -g

you'll get a little more debug info that way, like the line in the code that actually causes the problem.  Also, it would be good to know the lengths of the arrays in the input, to see that they are indeed all the same length.  Could be a bug in my code, or that something got off in the set up, but there's not enough to go on at the moment.  

So, send me the info, and we'll work from there.

Cheers,


Mike
