[gradsusr] setting time with intervals

[Sagar P Parajuli]

Hi Jeff,
I think I didn't clarify my question. I am writing control file for
extracting some wind speed data corresponding to particular time of a day.
What I could do in grads is:
 set t 1 last
But I want to do this skipping certain values eg. I want values
corresponding to t = 1, 3, 5, 7, 9, etc (i.e. with certain interval). So, I
need to skip some data and only extract those datas.
How can I do this?


Thank you so much again.



Sagar
