operands cannot be broadcast together with shapes

Post by aewindle110 »

I am trying to run Polymer on subsetted OLCI scenes (subsetted using SNAP GPT) but am getting this error:

Code: Select all

[code]python new_batch_proc_nasa.py
/media/silsbelab/S33/S3_L1/Subset_S3_L1/nc_files/S3A/new/subset_S3A_OL_1_EFR____20190724T144907_20190724T145207_20190725T203720_0179_047_196_2340_MAR_O_NT_002.nc

[/code]

Is there an easy fix to this or has the subsetting caused this error?

Hello,
Processing SNAP subsetted files is currently not supported, these files are not of the same format as the Level1 SAFE products.
However if you are interested in processing a subset, you can do so using the sline, eline, scol and ecol parameters ; see example.py
Cheers,
François
