@rapidsna My recent commits try to address a lot of the issues you brought up. If the FAM's array index is negative or out of bounds, it should now catch it and return an appropriate value. There may still be some corner cases that have to be hammered out, but I'd like to get this in if you feel it's ready, as I think the corner cases will occur infrequently.
