Hi there,
I experience a peculiar error when trying to read S3 OLCI NRT products using snappy / Snap 6.0 / python 2.7: If the name of the containing folder contains an underscore (’_’) in the 13. position, snappy will crash with a nondiscriptive error message (“Cannot read product file”). Unfortunately, this is the case in the default naming convention (naming example see below):
S3A_OL_1_EFR____20180707T175541_20180707T175638_20180707T203026_0057_033_141_1080_O_NR_002
changing the containing folder name to, e.g. (notice the ‘X’):
S3A_OL_1_EFRX___20180707T175541_20180707T175638_20180707T203026_0057_033_141_1080_O_NR_002
solves the problem.
Best regards, mno
