Thanks for reporting the problem, which happens to files with "maifest.safe". We'll try to fix the problem. The work around is 1. add the -r or --refreshDB option getanc -v -r /Volumes/Tlin/LIS/LISCO/S2_MSI_L1_H/S2A_MSIL1C_20210102T154641_N0209_R011_T18TXL_20210102T174143.SAFE/manifest.saf...

MSI_S2A L1 file for 2023 has a new format compared to 2021, we need to figure out a way to read the L1 file with the new format for l2gen to work right and we will update here once we do.

I tired l2gen on AQUA_MODIS.20230220T011000.L1B.hdf with north=22, south=12, east=-175, west=175.. I got the L2 file with the southwest point (176.85, 12.91) and northeast point (-175.47, 23.65). The x dimension is 0 to 682 pixels. I don't understand what you meant by "extremly large x dimensio...
