 v21 Probably it will fail in the first attempt, so don't worry. If it fails, see wrf4g exp --help to look for the errors. Once the test experiment has run successfully, you should check that the output looks fine and that it contains all the variables that you want. Tools like [http://meteora.ucsd.edu/~pierce/ncview_home_page.html ncview] and [https://www.unidata.ucar.edu/software/netcdf/docs/ncdump-man-1.html ncdump] are very useful for this task. This step is specially important if you are using a [wiki:WRF4G2.0/Postprocessor postprocessor] in WRF4G to filter variables because of disk space limitations.
