You can use SeaDAS to view/inspect GOCI-II L1B files but the mission is not supported by our processing software (l2gen, getanc, etc).

What version of l2bin are you using? Could you provide the full log? I ran it with l2bin 8.1.1 and saw no I issue. Could you try to run V2026.0, the most recent V tag? l2bin ifile=PACE_OCI.20250401T153859.L2.OC_AOP.V3_1.nc ofile=test.nc suite=RRS l2bin 8.1.1 (Mar 25 2026 05:21:28) Loading default pa...

Also, could you compare the output files produced with the V2023 and V2025 tags? An L2 file has a group named processing controls, which contains all the input parameters and files. These should be the same in both tags.

I ran l2gen 9.11.0-V2025.1 (Jan 30 2025 23:47:26) on a Red Hat Enterprise Linux release 8.5 (Ootpa) with AMD EPYC 7352 24-Core Processor. CPU usage was close to 100% all the time and the RSS was around 4.3 Gb I used the same input file and the same input parameter as you did. I ran the code directly...

Could you please provide the file name and explain exactly how you run the code?

There are 2 viable solutions. 1) change OCSSW_bash.env: replace line 81 with the following expression if [ -z ${OCDATAROOT+x} ]; then export OCDATAROOT=$OCSSWROOT/share; else echo "OCDATAROOT is set to '$OCDATAROOT'"; fi replace line 84 with the following expression if [ -z ${OCVARROOT+x} ...
