You can access CDAT as normal user. In fact it will be accessible by all
users if it has installed in the path /usr/local.

Your IO error says that you do not have write access.
I guess you are trying to write the variable to netcdf out file.
You make sure that you have write access in location (directory) where the
outfile is specified.

Also I would suggest you to join & post queries in UV-CDAT mailing list.
