L2bin Prodtype 8-day

Dear All,
I would like to ask. I've tried many times to use both command and GUI to process 8-day l2bin prodtype from MODIS Aqua data. However, it didn't work and always show this result

129 input files

We'll need more information to help diagnose the issue. Please provide the command-line arguments (and/or the parameter file used) as well as a description of how the input L2 files were obtained (or generated).

The script process for l2bin to generate l3mapgen and l3bindump. Nonetheless, l2bin doesn't work. Data obtained from L2 MODIS-Aqua for chlorophyll-a product compiling at txt file.

Thank you

OK, a couple of things to note here. The l2bin options for sday/eday are only useful when binning global data and are unnecessary for a regional binning (even if that regional binning includes 8 days worth of source L2 data). Also, the prodtype option should be set to 'regional' if you are not trying to bin data covering the entire globe.

The following should work for you:

l2bin ifile=$file1 ofile=January2021_l3bin8day1.nc latnorth=45 latsouth=40 loneast=150 lonwest=140 resolution=1 flaguse=$flaguse l3bprod=chlor_a prodtype=regional
