Re: [Cdat-discussion] Strange error when using cdat as non-root

[sudipta s. <sdp...@gm...>]

Hi Arulalan
I am not trying to write to any file. All I am trying to do is to call the
"cdutil.CLIMATOLOGY.departures" function and I get this error. I am not
sure if the function internally tries to write to a location that is not
accessible as a non root.
