Mapgen return error 110

[c_rojas]

Hi,

I'm trying to learn how to generate true color images using Modis imagery. So far I have no problems with some files, but with others mapgen keeps failing. I'm interested in understand why fails for some files and not for others. Whether is something that I'm doing wrong or is a problem with the files, or my local configuration.

With the following file, fails for example:
http://oceandata.sci.gsfc.nasa.gov/getfile/A2023235064000.L1A_LAC.bz2

What I do is:
1. I use modis_GEO
modis_GEO File*.L1A_LAC
2. Then modis_L1B
modis_L1B File*L1A_LAC File*GEO.hdf
3. Finally, mapgen
mappgen --ifile File*.L1B.hdf --geofile File*.GEO.hdf --use_rgb

With the previous file, mapgen generate the following log file:
-ERROR- 2025-08-15 16:44:22,855 - Exiting: /SeaDAS/ocssw/bin/l2bin flaguse=ATMFAIL,BOWTIEDEL ifile=mapgen_l2gen_list.txt ofile=mapgen_tmp.l2bin.nc area_weighting=1 prodtype=regional resolution=1 returned a status 110

As I said before, for some files this works but not for all of them. Any advice on what the problem could be?

I'm using SeaDas 9.2.0 with OCSSW (2025.1) on Debian 12.

Thanks!

Status 110 is typically returned when there is no data to process.

A2023235064000.L1A_LAC is a night granule so the visible bands are not available
