Hi,
The xml file does not like && ! Any way I am  going to use IDL to do mosaics as I want minimum, mean, and median values  for the mosaics.
Thanks for your help.

Hello,  Could you please  explain the following segment in the xml file from https://seadas.gsfc.nasa.gov/help/GptCookbook/gptCookbookMosaic.html    <conditions>            <condition>                <name>cond...

I am not using GUI -- in GUI I see NaNs!
In the Parameter file is there way to fix this?
Thanks for your help.

Thanks. Here is a portion of what I get after I use gpt to mosaic files:metadata:Processing_Graph:node_0:parameters:orthorectify = "false" ;                metadata:Processing_Graph:node_0:parameters:combine = "OR" ;     
...

I just look at ncdump of the L2 nc file.
Thanks.

In the GUI I can see NaN where there is no data (Rhos =0  there show up as NaN) it is the NetCDF file that they stay 0s and no appear as NaN. I tried a number (-9999) instead of NaN but that does not work either!
Thanks much for your help.

Hello George,  Thank you for the explanation. What I want to do is exclude land and cloud pixels from mosaic/composite and then set rhos to NaN or some missing value number if the value is 0. My par file looks like this:band1=rhos_412band1Expression=if (rhos_412 != 0) then rhos_412 else NaNqual...

Hello,  I am doing mosaic of a few mages and want to set certain value to NaN  I followed this statement in .par file:  band1Expression=if (Kd_490 != 0) then 1.3/Kd_490 else NaN   and have a statement that looks like:   band1Expression=if (rhos_443 != 0) then rhos_...
