Sentinel-1 data TOPS parameter file insufficient length
Added by Yi Zang about 9 years ago
Hello all,
I was using Gamma software doing co-registration for Sentinel-1 data using scripts: S1_coreg_TOPS. I used par_S1_SLC to convert the raw data to .slc .slc.par and TOPS_par file formats and then used s1_coreg_TOPS to do co registration. But the program gives me this error:
"Reading TOPS parameter file, insufficient file length!"
However, the TOPS parameter file I have has all the information about the burst and so on. I have attached a TOPS_par file in the attachment. I did no change to this file. This same error is also shown when I was trying to generate SLC mosaic using SLC_mosaic_S1_TOPS.
Any idea of what's gone wrong?
Any help is appreciated!
Yi

Hello,
This is an issue with running the software on Windows.
The end of line characters in Windows are CR/LF, while in Unix uses just a LF.
hence the file has
the wrong length on Windows.

Hello,
I have uploaded a new versions of the Gamma software for Windows (64-bit).
This is a preliminary version of the GAMMA software before our semi-annual
release in December.
I have fixed the issue with reading TOPS parameter files in Windows as well as a
number of other windows related bugs. You can download the software from our
server using the same download information that you had when you downloaded the
software in July.
This update is highly recommended if you use Cosmo-Skymed or PALSAR2 data.
Let me know if you find other issues.
Best regards,
Charles Werner
