Hi,
No body can help you other than yourself ! I am pretty sure that there is
problem with your execution of commands. I don't see any problem with data
or the process to calculate temporal correlation.
Anyway, attach your .gs file to let me check if any issues are there in
your code.
Regards,
Kishore
