Sir.
I am working on GPR attribute analysis in OpendTect software. I have tried to upload the file in the software by import-->Seismics-->GPR: DZT and uploaded the file without changing the other settings (like Z factor). After uploading I am unable to visualise the file in the software. I have also tried to upload by import-->Seismics-->Simple File--> Line. Still the section is not visible in the software. 
Please help me in the problem and give some step by step guide (if available) for this analysis.

Thanking you.
Arnab Kumar Pal

Hello Arnab,

If you loaded the GPR data into an existing OpendTect survey, you should apply a Z scalar to match the sampling rates of GPR file and Survey setup. Try a factor of 1000 and see what happens. 

Before you do this, you could first check in the seismic manager if the data is loaded in OpendTect. If so, try adding the line and displaying it with a 2D viewer. If that works, the problem is probably the Z scalar which you can set in the GPR import window.

I hope this helps. Best regards,

Paul.

Thank you sir for your quick response. I have tried to change the Z factor value to 1000, but the data is still not visible. I have also checked in the seismic manager tool and the GPR line is available there. I have attached a screenshot of the scene for reference.

Thanking you

Hi Arnab,

Support will contact you and take over this problem. When it is solved, they will come back with the solution in this forum. 

In the meantime, please right-click on the entry in the tree and select Display -> 2D Viewer to see if the data can be displayed.

Best regards,

Paul.
