Hi, I have the same problem. Is geopsyhv with -slot 3 supposed to write out anything? geopsy -tool geopsyhv -slot 3 test.mseed -- -param test.log -save test -autowin When I use the gui version and specify the output directory, no results are written either. I'm using version geopsypack-2.10.1. Thank...

Hi Marc, Just upgraded dinver to the latest version. I have seen that the "-batch" option of command line dinver is no longer available. Instead one can use "-optimization". Is it still possible to start several processes at the same time and create report files like *_0?.report ...

Just talked to Valerie. She also still has the original version. She will check what modifications she made we may need. I will come back to you ...

Apart from the licence question, which we have to solve somehow, do you have access to Saitos code, Marc? I'm working with a version, which has been modified a bit by Valerie Maupin since the code arrived in Oslo 20 years ago. But we could prepare or find a clean version and send it to you.

The code was originally distributed with the book from 1988 "Seismological Algorithms: Computational Methods and Computer Programs". Saitos package was called "DISPER80: A subroutine package for the calculation of seismic normal-mode solutions". The book says that everyone who wa...

Yes, using Saito for forward computation would be the "cleanest" or most accurate solution. Would it be possible to include a fortran code directly as a plugin or has it to be rewritten in cpp? I could forward you the code if you want to have a look. I compared the Saito (spherical) and di...

There are basically three ways to take into account the spherical earth: 1. Correct phase velocities empirically (don't have to change anything in dinver). Bhattacharyam, 1976 is showing a plot of that relation (Fig 1), but I also tried to find one by myself by simply generating random models (gppar...

We are using the program of Saito for the forward computation in a spherical earth. The problem may be that it is written in fortran and, more serious, that it needs much more computation time than computing velocities from a layered model in a flat earth. In order to take into account the spherical...

Hi Marc, I'm using dinver to invert phase velocities at longer periods (noise cross-correlation). From about 20 s period, it starts to have a significant effect on phase velocities whether they are computed from a flat or from a spherical earth model. I was just wondering if it would be straight for...
