Re: why different answers from same data using different Geopsy Dinver releases?

Hi Marc, tried to repeat your inversion following your track. I resampled the two curves in the 0.1Hz-25Hz range with 50 samples. I adopted what I believe was your final model (6 layers with the last two before the half-space confined between 60m and 200m and 80m and 200m). I used Dinver 3.3.5 with ...

Re: why different answers from same data using different Geopsy Dinver releases?

Hi Marc, first I would like to thank you for the excellent joint reversal demonstration, impossible for me to successfully complete with the help of only published technical documentation. At the site to which the data refer, 6 night-time single station measurements were carried out lasting 120 minu...

Re: Export Microtremor Results in Frequency domain

Hi Marc Taking up the final part of your answer I ask you why if in the header of my Saf file I impose that the data units are m / s the ordinate of the PSD is always (counts) ^ 2 / Hz? SESAME ASCII data format (saf) v. 1 (this line must not be modified) SAMP_FREQ = 125 NDAT = 675000 START_TIME = 20...

Re: why different answers from same data using different Geopsy Dinver releases?

Hi Marc, I did as suggested and I got the Marc.dinver file from the 3.3.4 release where you can see from the different runs how the misfit value is very variable and high. On the contrary, the marc2.dinver file obteined by the 2.9.0 release has not only lower misfit values, but also decidedly more s...

Re: gphistogram for plotting azimuth vs freq or slowness data from max file

Hi Marc, from your words I understand that you have successfully checked the .max file created with the 2.9.0 release with the new 3.5 branch although the parsing is different from what you get with the branches after 3.0. In these, in fact, the slowness is at column 4 and the azimuth at 5, while in...

Hi Marc,
Can you send me the original HRFK.max file?
I attach the file

Thanks

Hi Marc,
sorry but what do you mean by .dinver file? the dinver ground profiles models or the dinver app 3.4, or the ellipt.txt and disper.txt, or ...

Re: gphistogram for plotting azimuth vs freq or slowness data from max file

Hi Marc, thanks. In documentation I found awk 'substr($1,1,1)!="#" {print $4, $3}' my.max |\ gphistogram -x-min -0 -x-max 360 -x-count 72 -x-sampling linear \ -y-min 0 -y-max 8 -y-count 100 -y-sampling linear and the error message is: awk command not found (as you wrote). the command lines you indi...

gphistogram for plotting azimuth vs freq or slowness data from max file

Hi Marc,
I want to ask you, please, how can I plot the azimuth vs frequency or vs slowness data of a max file using Geopsyland. The command line in the documentation isn't accepted, of course, so is there another command or an other way to represent that data?
Thanks
Luigi

why different answers from same data using different Geopsy Dinver releases?

Hi Marc, as already mentioned in my topic 402 (last post) I found different answers from the joint inversion using Dinver of the 2.9.0 release to that of the 3 series and I don't understand why. I am attaching the example of the same ellipticity curve (right flank of the peak) and of the same disper...

N/V or E/V it is possible to do?

Hi Marc, I wonder if it is possible to obtain the spectral ratio from only one horizontal component (N / V or E / V). In many works I have noticed that this option is often used to enhance the non 1D response conditions of the geological context. I tried to load only 2 components (V and 1H) but Geop...

Re: Axes in particle motion plots

Hi Marc, As suggested I have manually expanded but as you can see the plot is empty and this happens on all releases after 2.9. The one shown is related to release 3.3.3. and the same happens with 3.3.4. So I have to keep several releases active on my PC to take advantage of all the potential of Geo...

3.3.4. release still crashes saving hv file

Hi Marc I downloaded the Windows 3.3.4 release but it is still not possible to save the hv files and the software crashes. Except release 3.1.0. no other series 3 allows saving hv files and is capable of reading .log files saved with that release. The following message appears in the log window: Add...
