Thanks George,

I get the same core dump when producing sst_tripple on a MODIS file. We will enter a bug report. L2gen should catch products that can not be produced and print out a reasonable error.

Actually I had to fix a few things in the CMakeLists.txt file. You will need to use "--tag T2021.23". You will not be able to build the VIIRS code so do not turn on the BUILD_ALL or BUILD_VIIRS_L1 flag for cmake. The process becomes: export OCSSWROOT=/home/colapao/seadas-7.5.3/ocssw instal...

I would suggest not building the VIIRS part for now. I have to make a few sets of libraries to export for that to work. Try this:
Let me know how that works.

All of the programs you mentioned read the product.xml file. Here is a minimum product entry: </product> <product name="my_new_product"> <units>m s^-1</units> <category>Derived</category> <range> <validMin>0</validMin> <validMax>50</validMax> <displayMin>0</displayMin> <displayMax>20</disp...

Yes, the n,s,e,w params for l2gen are more convenient than grabbing the output of lonlat2pixline. I am almost done fixing the bug. Expect the fix in the next release.

Thanks again for finding this.

OK, looks like the n,s,e,w params for l2gen processing VIIRS has a nasty bug in it. Here is what I suggest for your processing stream. - run lonlat2pixline with the GEO file and n,s,e,w to get start/end, line/pixel for region of interest - run l2gen with L1A and GEO file and start/end, line/pixel pa...

I can reproduce the seg fault on my Linux machine. Seems to work fine on my mac, but that is how these memory issues usually behave. There is an easy work around that you can put into your processing stream. l2gen works fine if you use an L1B file as the ifile instead of an L1A. Using the example fi...

The best way to solve this is to write a GOCI-II reader for l2gen. Currently, we do not have plans to write one. We do supply the source code, so others can contribute. Here is what I see as the major issues for you: - l2gen is written in C/C++, so it is easiest to write the reader in C++. - l2gen d...

Can you give me the exact command lines you are using to go from V2016258230600.L1A_SNPP.nc to the subsetted files that makes l2gen crash? I will try to reproduce the crash here.

Both getanc and l2gen work fine for me with that file. What OCSSW tag did you install? I would first try to download the VIIRS file again since l2gen could not figure what type the file is.
