[gradsusr] daily climo akin to monthly climo?

[Muthuvel Chelliah]

Dear Grads Gurus,

Here is something to ponder.
In grads if we have long monthly data, we all know
we can compute monthly climo by, for example,

set t 1 12
define monclimo=ave(monthlydata,t+0,t=N,12)
set t 1 N
modify monclimo seasonal.

In the same way, if I want to compute a quick and dirty daily climo,
and if had daily data for many years, I did,

set t 1 365
define dailyclimo=ave(dailydata,t+0,t=M,365)

the above step works, and the values look correct.
But the following step does not work!!

modify dailyclimo seasonal

It says:
MODIFY Error:  Invalid time scaling in defined variable

Any ideas/suggestions? or is this not possible to do :-(

Thanks in advance!!

Muthu
