Hello, Was a solution to this problem identified? I am running into the same issue with 'raster overflow'. I'm running version 6.3 Beta on a 64 bit machine with 12GB of RAM. When I execute SLAMM on my data the "counting cells to track" gets to 31% and then I get an error "integer overflow". Is there a work around for this? I looked on the forum and didn't find an answer. I am working with some rather large datasets and I wonder if it is a SLAMM limitation???

Thanks John Guinotte
