SeaDAS 10.0 Windows fails to open GOCI L1B (NASA source)

"Hi SeaDAS Team, I am using SeaDAS 10.0.0 on Windows 11. I downloaded GOCI-1 L1B data (COMS_GOCI_L1B_GA_20200816031640.he5) directly from the NASA Ocean Color website (Level-1B browser). When I drag the file into SeaDAS, or use 'Import -> Optical Sensors -> GOCI', I get the error: "No appropriate product reader found". The file path is short and has no spaces (D:\GOCI\). Is this a known bug in SeaDAS 10 for Windows? How can I open this file?"

The GOCI L1B data are stored as compressed files on our archive, but when you download it, the downloaded file will not have the compression suffix. (gz or zip)

Try running the file command on the L1B file to ensure it is not compressed.
