[gradsusr] starting grads

Sepideh, it should work for all files as long as they are in the %y4 directory. I put your data file under a 2009 directory and opened it with GrADS. The output is below. There does seem to be a problem with your data. John

thanks for the answer
the version that i am using is 2.0 a8
my main problem is do i have to make a control file for every one of the files that i want to read?
I have a bunch of daily precipitations,that i attach one of them, but i just have one control file and i have no idea if that is just a sample, or it works for all of the files.

the first one is the only control file that i have and the second one is precipitation for 01/04/2009

Hi Sepideh,

You are going to have to give us more information. Try and be more focused on the GrADS files you are using, show us an example of one of the CTL files, give us a link to the data files, and tell us what version of GrADS you are using with the 'q config' command.

Hi,
Can anyone help me with this problem:
I have a set of data with the extension of .lnx, and i have the control file for them.
I open the control file, but i don't know how to read the data afterward.

thanks
