Thank you for the suggestion, Sean. I will look into that. So when I use 'reproject' from the GUI, does it do any resampling or binning? How to decide that factor?
I am grateful to all of you from this forum for patently helping with these questions.

Hi Sean,
    I ran l2gen for OLI - but I am sure it used the climatology data. On the GUI it is simple to select 'Get Ancillary' but I do not see how to set this  in command line parameters.
Thanks.

Thanks so much for your reply. I tried running l2gen in bash and it seems to be working! At  least I did not get the error - and the program is going through
execution steps!
Thanks again.
