Snappy / SNAP 6.0 product file reading bug

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

Update: It seems that the problem arose due to me editing the folder name in the first place (by removing the processing facility ID). So, actually, it does work with the default naming. One just has to make sure to leave the directory name absolutely untouched (at least, not change the number of underscores).

Cheers, mno
