modis L1B

by ocabrera » Tue Nov 23, 2021 9:04 pm America/New_York

I am trying to process L1A files in seadas (Windows with UBUNTU System)
but I am receiving an error as below. When i do a search for invalid cross-link, it has to do with source and target names, but I do not know where this is being set.

====
execution exception: java.io.IOException: modis_L1B failed with exit code 1.
Check log for more details.
