Dear Support,
for a while now I've also been experiencing the same problem with getanc no longer returning the proper ancillary information for Sentinel-3, just referring to non optimal MET, OZONE ... files and generating an empty file.
Thanks for any help,
Best, F.

Dear Support,
you mentioned the possibility of a new tag release (V2025.6 ?) but it seems that we are still at V2025.5. Would you know when a new official release (that would include the fix on the slowness) could come? Thanks a lot! Best, F.

Dear all,
I confirm that version T2025.15 has fixed the problem of l2gen being slow. Wonderful!
Looking forward to the next 'V' release !
Thanks a lot,
Best, F.

Dear Sean,
this would be wonderful, thanks a lot! I'll watch for the new test version and release.
Best,

Dear Sean and Roger,
thanks a lot for the feedback! This could really mean a lot for us.
If I understand well, it means updating setanc.c but there would be a need for quite a compiling effort, wouldn't there ? Or could we expect a software update in the short term?
Thanks again!
Best, F.

Dear Alex, thanks a lot for your feedback, this is really appreciated. I am also using l2gen on the command line (from a shell, I tried csh and bash). The test image I am using is actually ~ twice smaller (7848 lines) because it is cut at 10 deg. North. With l2gen associated with V2023 (9.6.0-V2023....

Dear Support, the example I'm using (processing a S3A image) is l2gen par=./l2gen.par (l2gen Version 9.11.0-V2025.1 ) with l2gen.par containing: ifile=S3A_OL_1_ERR____20170516T112404_20170516T120828_20180420T162232_2664_017_351______LR2_R_NT_002_x/xfdumanifest.xml ofile1=./O2017136112404.L2_S3A.nc l...

Dear Support,
to continue testing, could you please update me on which OS versions are recommended to run V2025 ? I see references in some help pages but they seem to point to rather old releases of Ubuntu or CentOS .
Thanks a lot!
Best, f.

Dear Support, I am still looking desperately for a reason for the decrease in speed for l2gen between V2023 and 2024-2025. For instance the processing of a S3A large image takes 8 times longer. I am using only default options, and the only difference I've seen is the addition of absaer_opt=0 is the ...

Dear Support,
sorry for the slow reply. Our machines have Xeon CPUs running RHEL 8.10 as OS. When I source SeaDAS to V2023.3, l2gen goes fast, while if it is V2025.1, it is very slow. Do you have an idea of why this could happen?
Thnaks,
Best, F.
