Re: No export to .max MSPAC

Hi Joe,

This is planned to be re-introduced in a future release (especially, if users are asking for it!).
You probably have to go back to 2.10 or so to be sure to have to feature working.

Best regards,

Marc

Re: How split data with geopsy?

Hi, In waveform menu you can cut signals between two absolute times. Then export (menu file) cut traces to another file. You can do that for all stations of the array with a single operation. It is also possible to do the same thing inside a script but it is a bit more complex. If you have to proces...

Re: Geopsy (3.3.0-1-2) H/V tool doesn't read the *.log file

Hi Luigi, Thanks for your report. There is no simple way to work around this issue right now because the time was saved relative to the beginning of the signal and it is now an absolute time with format "yyyyMMddhhmmssz". I will add some code that offers some compatibility. I don't think that it wil...

Re: ERROR INSTALLATION IN UBUNTU 20.04

Hi Nanda, Good to read that you finally found a solution. Any particular error you fixed with Qt 5.15? I've never tried it, I'm still with Qt 5.14. If you still have the 3.4 folder available, I would be curious to get the full log (re-run make in it). The ending part you provided does not contain al...

Re: fk parameter) 'RELATIVE_THRESHOLD (%) = '

By default 90% threshold is used. So specifying 90% should not change the results. Do you get something different if you set 10%?

Hi,

Can you try with 3.3.2 or even better from the git repository with 3.3.3-preview?
See download page to access the git repository.

Effectively, this not fixed in 3.3.2 but for 3.3.3
It will be available soon.

Re: GeoPsy crashes when attempting to save results

Hi, From the crash report, I can read that you were using version 3.3.1. This problem is fixed in 3.3.2 available from download page. To export results, you may also use geopsy-hv from a terminal. See" -h all" for the details of the available options. Or search ths forum and the wiki, there are othe...

Re: EHVSR

Geopsy is primarily designed for computing HVSR from ambient vibrations (microtremors) but it can also compute spectral ratios for earthquakes. I have little experience with earthquake data and I can't help you. Check the literature.

Re: Difference betwen seismic file format

-For XY coordinates, there is factor and another one for the Z that you can define in the SEGY header. It is a bit tricky to use these factors. Here is the code in geopsy to get the true factor value from the header value. if(field.coordinateFactor>0) { return field.coordinateFactor; } else if(field...

Re: gphistogram have an anomalous grapfic output

Answers to your message posted on 02 Aug 3:32 pm. If you derived a dispersion curve from the autocorr curve, it is useless to invert the autocorr and the dispersion. You are free to choose one of the two options but not both at the same time. Both objects contain the same information. If I remember ...

Re: SPAC and spac2disp doesn't run with the 3.3.2. release

OK I could reproduce the error while processing 3C SPAC. It was a wrong initialization of the horizontal cross-spectrum matrix. The processing of 3C SPAC targets is still experimental. You must start spac2disp with option '-VRT'. If not, you will get an error complaining that there are 3 curves per ...

Re: gphistogram have an anomalous grapfic output

In dinver target, select "Peak frequency", and just enter the value. You will see that playing with the relative weight of sub-targets is necessary to achieve a reasonable fit of the dispersion curve. An alternative and better way is to set a minimum misfit for all sub-targets. Once the minimum misf...

For source coordinates, sourceXCoordinate and sourceYCoordinate , also from trace header (offsets 73-76 and 77-80, respectively). The event is systematically crea...
