Dear author,
The csi is a good tool package for seismic inversion. But there is omitted the EDKS code when using the multilayered media. I found the home web of prof. Zhu(https://www.eas.slu.edu/People/LZhu/home.html. However, it is not on that web. Could you provide the available link to the code, thank you.

Dear @ThreeIcug,

The EDKS code is not a part of the CSI package. It was developed at Caltech some years ago, but as far as I know, it is not available online at this time.

Dear @EJFielding
Thank you. If I want to use the multilayered media by CSI, are there other alternatives method?
In addition, I send an email to Prof. Zhu. He said the code is called FK which is available on his home page. But this does not match the calling function in CSI.

Sorry, I don't know about the different seismology codes for layered elastic half-space calculations. It sounds like Prof. Lupei Zhu has modified the EDKS code to use a different set of calling functions. The CSI code was designed to use the EDKS package. Maybe Prof. Zhu still has the older EDKS code somewhere.

There are some difficulties in using EDKS in CSI, but it seems that Pr. Wang Rongjiang's FORTRAN programs EDGRN/EDCMP can also calculate green's function using a layered semi-infinite elastic medium.
May I ask what is the difference between Pr. Wang's method and Pr. Zhu's method in calculating the Green's function for multilayer media? or
Is it possible to use wang's program to compute the Green's function independently instead of zhu's method?
