Thanks Marc.

I did not find the help message for "utm", but I solved using the relative metric coordinates (x and y) in USER7 and USER8.

You are the greatest.

Hi Marc, I'm trying to use the geopsy fk trough command line to estimate dispersion curves, I have problems to load files coordinates. My dataset is composed of sac files, and the headers of station name, latitude and longitude are correctly set (stla and stlo in case of sac). I do not use geopsy da...

Hi Marc My question is on the possibilities to perform basic waveform operations (i.e. taper cut merge etc..) not using the GUI but using a command line. Is there the possibility to do it? I guess I should use the commands appearing in Waveform console such as taper("Rectangular", "[s...

Hi Marc it means that to obtain R and L waves I have to run geopsy-fk two times, firstly with the RTBF option in order to obtain the R dispersion curve and then with the CaponTransverse option to obtain only the Love waves. In the second case, I attach the Love curves obtained consistently with the ...

Dear Marc, I have a question on the use of gpviemax or gphistogram of the new release 3.4.1, after a RTBF analysis performed on 3C passive data. gpviemax produces always a result as in attach; I mean using no option, or using the option -R the output does not change (this is what I argue). The outpu...

Perfect Marc. I had misinterpreted the output *spec file, now clear thanks you answer.
solved !!

Thanks Marc, the script works; tested with the 3.4.1 release. For the Spectra, in the output *Z.spec file for each angle I have a spectrum. But I would like to individually save the rotated EW and NS components. Or in other words, the script on rotate spectra works using 3C data as input, but I cann...

Hi Marc my aim is to get (and save as ascci file) rotated spectra for regular bins for the components of motion. I mean not H/V but the spectra of the single component. I have a vague remind that it was possible with the very old release of geopsy. Now I use the tool Spectrum Rotate, but it seems to...

The five steps suggested by tsonne work also
on ubuntu 13.10 64bit (saucy)
for the installation of geopsypackage 2.5.0

Hi Marc, I am wondering if it is possible to forward compute theoretical spatial autocorrelation curves assuming a known layered model (or in other words a theoretical dispersion curve) and a known geometry of receivers. spac2disp links autocorrelation and dispersion curve, but it seems me not in a ...

Hi Marc,
I am wondering if is possible, within the geopsy tools, to compute the 1D response of a large numbers of models using alternative program to gpsh.
The models are the output of gpviewdcreport.

Thanks
Giuseppe

Hi, my question is about joint inversion of more than one targets. In my case, I want to invert three autocorrelation curves and an ellipticity peak. Dinver (last snapshot of May under windows) returns the following message before to crash: The effective number of samples for dispersion curve is gre...

I am using gpsh with the snapshot of May under windows. My input file for gpsh was produced by gpviewdcreport. I selected through gpviewdcreport an inversion report (run*_report), and with the tool export model I created the model file (it should be in attach). This model file is correctly used as i...

Hi, I am using the linear fk on active data. In particular I am trying to investigate the effect of normalization on the dispersion curve. From a theoretical point of view the normalization using sqrt of distance is correct working with surface waves. Although this, it seems me that: 1) the normaliz...

Hi Marc, the dinver in my pc (last snapshot distributed in May) allows to select the maximum misfit limited to the forth decimal numbers (0.000?). Now the problem is that, after the inversion, I have a misfit very low (2.1e-6), and the viewer to see the inversion results (I mean ground profiles view...
