Hello everybody,
Edit : Snap version 4 or 5 under ubuntu 16.04
with more investigation, the difference between subset in GUI or using gpt is that with gpt I miss “Original_Product_Metadata” even with -PcopyMetadata==true options
I am working on script that do a subset using the extent of a shape file converted in WKT to do a subset of Sentinel-1 data.
I use the following command that is running well.
gpt Subset -SsourceProduct=/home/onfi/TMP/KitWorkshop/Demo/Data/S1/S1A_IW_GRDH_1SDV_20160119T092453_20160119T092518_009561_00DE6B_121F.SAFE/manifest.safe -PcopyMetadata==true -PgeoRegion=‘Polygon ((-57.6505929553 -12.3331525573, -57.0078619743 -12.3331525573, -57.0078619743 -11.8247169762, -57.6505929553 -11.8247169762, -57.6505929553 -12.3331525573))’ -t /home/onfi/TMP/TestClipS1Snap/clipsnap1.dim
However, when after I want to do calibration (or thermal noise removal) I have the following error (not when I apply precise orbit)
Command
gpt Calibration -Ssource=/home/onfi/TMP/TestClipS1Snap/clipsnap1.dim -PoutputBetaBand=True -PoutputSigmaBand=false -t /home/onfi/TMP/TestClipS1Snap/clipsnap_cal.dim

Error: Unable to find calibration element in original product metadata
Even if I give subset using pixel I have the problem. However, what is a little bit strange is that using Snap desktop, subset is working well.
Maybe I need to add options in gpt.vmoptions ?
Thanks for help
