did snaphu give you any error? Based on your first image it looks like it didn’t even start.
I forgot to do one step. Now it is working. Thanks:slight_smile:
I got an error file while unwrapping using snaphu which says

Which step you had missed last time?? The error is same for me, so can you please write the steps for me. I am following steps as… Coregistration (TopSarSplit, AppOrbitFile, BackGeocoding) >> EAP Phase correction >> Interferogram Formation >> Top Debrust >> Topographic Phase Removal >> Goldstein Phase Filtering >> Snaphu Export (Did not generated Img file for Unwphase ) >> Snaphu Import (Not working).
Thank you in advance…!!
If I run it from Ubuntu Konsole then I have this ERROR:
compName:~/S1_test/Snap_Export/S1A_IW_SLC__1SDV_Orb_Stack_pc_Ifg_Deb_DInSAR_Flt$ sudo snaphu -f Phase_VV_05Dec2014_05Apr2017.snaphu.img 1721

Can anyone please help to correct me.

“I did have similar issues with this and on another forum found that the segmentation fault is likely due to the log file created by SNAPHU. In the snaphu.conf file comment out the log file line with a # and that should fix the problem”
#LOGFILE… in the snaphu.conf file is the solution. Now it is running. Great… Thanks again.
Is there a need to edit snaphu.conf file?
Are u using a manual for doing SNAPHU or not?
Hi, Thanks for your response. I am using these tutorials:
AND the Step Forum + some books…
I would be so happy if you could suggest us something more interesting.
Can anyone comment on the output. Am I correctly generated results or the visual expression giving any bad indication ??
hi, im following stripmap tutorial and im facing problem to unwrapping phase using snaphu in virtual linux. i did the step but when i checked the folder, there is no /vmshare/data/target_sanphu/ only /mnt/hgfs/ in file system. then i cant run the snaphu.conf even i made gedit snaphu.conf & in my /home/sar/ and copy paste the command to call snaphu
The tutorial dates back from a time when snaphu was only working on Linux and you had to use a virtual environment. In the meanwhile, you can download a windows executable here so you no longer need the virtual machine: http://step.esa.int/main/third-party-plugins-2/snaphu/
I’m a windows user. I’m this step at now. How should I proceed? Should I use a virtual machine? Would you help me, please? Thanking you in advance.
Download the latest distribution of snaphu here: http://step.esa.int/main/third-party-plugins-2/snaphu/ and make snaphu.exe available to your command line.
Open snaphu.conf (which you just exported) in a text editor and copy the command given there.
Run this command in with your shell in the same folder.

@ABraun Thank you for your reply. I applied everything as in video. Unfortunately, I received this error again. =(
-bash: Is: command not found”
Even so I continued. The process has begun. But I’m sure this is not true step.
ls is not important, it just shows you the files inside the directory.
What you show in your screenshot is exactly what is needed. snaphu will process all tiles and tell you when it is finished.
Ok then I will just wait for the process to be completed. =) Thank you so much for your help.
I have been waiting for the completion of the process since a day. I have received this error several times. I repeat the process, but the same problem. What should I do? Could you help me please?
your processed raster is quite large. Try using only a subset to see if it generally works. Maybe snaphu experienced a timeout because of the file size.
I wanted to apply the sample dataset to learn. “Napa Valley Earthquake.”
I already applied that step. it can be “spatial subset from view” step. As you say it takes a long time and it gives an error at the end.
In this case, is there a way to keep working? I’m sorry to ask so many questions.
