Hi Sulochan,

whether time is listed first or last depends on the application ... in R, it's listed last. In some other applications, it's listed first. So that's just one of those things, and doesn't mean anything is wrong.

Re the data not matching, I fear that is some other problem then start and count in the R get.var.ncdf() call not working correctly. I suggest you check the exact values you use for start and count. Using a time index of 1 in R gives you the first time entry.
