Re: [idvdevelopers] Idv netcdf problem

Hi Don,

I've uploaded a sample file in yousendit.com and sending you the link
here.You can download it from the link.

This is the file

http://www.yousendit.com/download/Q01INnFGUnJlaFR2Wmc9PQ

Let me know whether you can open it ?

There are other big files like over 1GB. I think the structure is the same.
