Sean, thank you for the help!
I had full functionality, once I realized csh was not installed properly.
After installing csh, as per bullet #6 on 'Installation Notes';
http://seadas.gsfc.nasa.gov/how_to_install.htmlI then sourced $SEADAS/config/seadas.env file
This allowed me to run l2bin, create appropriate textfile, and continue to l3bin/smigen.
I realize csh was to be installed before SEADAS. While I seem to have full functionality, does a reversal of installation cause any known errors?
Thanks again,
Tyson
