Re: Geopsy 2.10.1 installation problem

I managed to partially compile Qt 4.8.7 with gcc 6.3, except QtScript module due to errors in Javascript tools. I started the compilation of 2.10.1 and ran into the same errors as reported. There is a missing internal include path. You can fix this by running: ./configure -I /tmp/geopsypack-src-2.10...

Re: Geopsy 2.10.1 installation problem

Hi, This release is not supported any more. Even if you manage to solve the first problem, I'm unsure if you can get to the end without getting other errors. If you really need this old release, the easiest way is to test it under Windows (in a virtual machine). If I can re-install a Qt 4 on my mach...

Re: Ellipticity joint inversion vith DC using Dinver 3.3.0. and following relaeases

Hi Luigi, The first strange thing in your figure is the value of your data curve. Values must be restricted to -90 to 90 deg (or 0 to 90 deg. for absolute value). How did you import the curve into Dinver? 0 deg. corresponds to a null ellipticity, 90 deg. to an infinite ellipticity. If you have a pos...

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

Actually I get the identical result with both threshold 10 and 90. Strange, I'll check this feature. You can filter directly from the command line of gphistogram: "-rel-power 0.9", for 90% Can you show us a few lines of your .max file (data part)? I suspect some issues about the storage of the powe...

Re: Uploading a synthetic data in Geopsy: File cannot be read!

Hi, To read a text file (data organized in columns), data must begin from the first line. In your case (sent by email) the first lines are: 48 16384 0.000000e+000 4.858683e-010 ... [total=49 columns] ... -5.356799e-011 1.250000e-004 4.145977e-010 ... [total=49 columns] ... 2.776331e-011 ... [total=1...

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...

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%?

Can you try with 3.3.2 or even better from the git repository with 3.3.3-preview?

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.

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...
