Gpt AddElevation

Hi,
I am new in SNAP. I am trying to use gpt command in Ubuntu for get a DEM band. I know I have to use AddElevation to create DEM band but I don’t know how I have to write all. I tried next ways:

./gpt AddElevation -Pfile="/home/user/Documents/S1A_IW_GRDH_1SDV_20150205T183605_20150205T183625_004492_005823_1B3B.SAFE/measurements/1a-iw-grd-vv-20150205t183605-20150205t183625-004492-005823-001.tiff"

and

./gpt AddElevation -Pfile="/home/user/Documents/S1A_IW_GRDH_1SDV_20150205T183605_20150205T183625_004492_005823_1B3B.SAFE/"

but in both cases have ocurred errors. Can you help me, please? How must I use this command?

You need to use either the zip file S1A_…zip or if unzipped then use the manifest.safe

Thanks, now it works.

./gpt AddElevation /home/user/Documents/S1A_IW_GRDH_1SDV_20150907T061013_20150907T061038_007605_00A887_68C1.zip
