Trying a gpt command that works nicely with Radarsat, for Sentinel-1 I get this error (Ubuntu). For one scene the output result is processed anyway despite this messag
SEVERE: org.esa.snap.framework.dataio.ProductIO: Error attempting to read /home/max/Documents/SARtest/S1A_EW_GRDM_1SDH_20150514T070347_20150514T070447_005914_0079EB_D5B3.SAFE/manifest.SAFE with plugin reader org.esa.s2tbx.dataio.spot.SpotViewProductReaderPlugin@a567e72: null
however, for another one I get this error and S1TBX does not process my scene:
SEVERE: org.esa.snap.framework.dataio.ProductIO: Error attempting to read /home/max/Documents/SARtest/S1A_EW_GRDM_1SDH_20150514T070347_20150514T070447_005914_0079EB_D5B3.safe/manifest.safe with plugin reader org.esa.s2tbx.dataio.rapideye.RapidEyeL3ReaderPlugin@710d7aff: null

Command
gpt /home/max/Calib_Spk_reproj_LinDB_Barents.xml -Pfile="/home/max/S1A_EW_GRDM_1SDH_20150514T070347_20150514T070447.SAFE/manifest.SAFE" -t "/home/max/testS1.dim"
using this xml file https://github.com/npolar/RemoteSensing/blob/master/Nest/Calib_Spk_reproj_LinDB_Barents.xml
Any advice?
Just found out myself:
The issue was the use of capital letters for the *.safe file and another difference between NEST and S1TBX.
In NEST I had used this without problems, in SNAP this gives an error message.
-Pfile="/home/max/S1A_EW_GRDM_1SDH_20150514T070347_20150514T070447.safe/manifest.safe"
However, S1TBX (or is it me running on Linux Ubuntu now?) seems to be case sensitive. The folder name is *.SAFE and not *.safe.
Using this works:
-Pfile="/home/max/S1A_EW_GRDM_1SDH_20150514T070347_20150514T070447.SAFE/manifest.safe"
I did not have the time to reproduce it systematically, but it seems using manifest.SAFE instead of manifest.safe gives an error but a result, while using foldername.safe instead of foldername.SAFE makes gpt fail completely.
I am having a similar error with my Terrain Correction graph:
SEVERE: org.esa.snap.core.dataio.ProductIO: Error attempting to read S1A_IW_GRDH_1SDV_20191002T141015_20191002T141040_029281_0353C6_2FCF.zip with plugin reader org.esa.s1tbx.io.risat1.Risat1ProductReaderPlugIn@5232e3f1: null
What we all missed is that the WRONG product readers are selected for our data:
Max’s example shows: spot.SpotViewProductReaderPlugin, and rapideye.RapidEyeL3ReaderPlugin
Mine above shows: risat1.Risat1ProductReaderPlugIn
Obviously the product reader should be Sentinel-1.
My graph completes with the correct result, so my error is not fatal, and GPT Read must eventually figure out the correct reader.
I suggest that a possible work around that I am testing now is to specify the “formatName” as SENTINEL-1 in the graph to force Read to use the correct product reader.
