Dear Marc,
I'm facing trouble in inversion process. The ellipticity curve doesn't appear on my laptop, while when I run the same data on another PC, the curve appears.
Here I attached the screenshot.
Kindly need your help.
Thanks,
Anis

Re: No visualization of ellipticity curve
Hi Anis,
The minimum misfit you reached is 1.2.
Marc
The minimum misfit you reached is 1.2.
- Did you request a maximum misfit below this value when plotting the ellipticity results?
- Your target ellipticity, is it an absolute or a signed value? Plotting and target must be consistent.
- How did you obtain the ellipticity curve?
- Are you inverting only an ellipticity curve? If so, additional constrains from a dispersion curve or a narrow prior interval for shallow Vs is needed.

Re: No visualization of ellipticity curve
Hi Marc,
Thanks for your reply.
I try to answer your questions.
Did you request a maximum misfit below this value when plotting the ellipticity results?
- No, I didn't. I put the same misfit value when plotting.
Your target ellipticity, is it an absolute or a signed value? Plotting and target must be consistent.
- It is an absolute value and is already the same as plotting and target.
How did you obtain the ellipticity curve?
- Firstly I import the H/V curve, and then I input the parameters needed (Vp, Vs, Poisson ratio, density) and next I start to run the process.
Are you inverting only an ellipticity curve? If so, additional constrains from a dispersion curve or a narrow prior interval for shallow Vs is needed.
- Yes, only an ellipticity curve.
I don't know what exactly the problem is. I already followed the steps and did the same procedure to obtain the ellipticity curve. Sometimes the curve appears, but sometimes it doesn't.
Regards,
Anis
