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...

Re: Difference betwen seismic file format

For receiver coordinates, receiverXCoordinate and receiverYCoordinate from trace header are read (offsets 81-84 and 85-88, respectively). For source coordinates, sourceXCoordinate and sourceYCoordinate , also from trace header (offsets 73-76 and 77-80, respectively). The event is systematically crea...

if CURRDIR is set to $PWD at the beginning of your forward.sh, it should work.

Re: Diagonal lines on results of the conventional FK

Several remarks after having a look at your .max file. the shape of your array is not optimal: it is rather elongated which provides a good resolution power along direction 25 deg. but rather poor in the perpendicular direction. We always try to get similar responses in all directions which is obtai...

Re: Bug report cannot be sent

Hi Martin,

Did you try with 3.3.2? I think that most of the issues have been solved with this version.

Re: Windows installation

Hi Sorry for responding so late. If you want to compile under Windows. You first have to install Qt 5. I use Qt 5.12.3 but it should work also with Qt 5.14. Qt 5.15 has never been tested. Install Qt from the graphical wizard. Under Windows, you can also install git. Even if you do not access to the ...

Re: SPAC use

Hi,

This is probably too late. In which application do you get this message? In spac2disp? In dinver? Normally fresh .target file generated by geopsy contain only one autocorr curve per ring.

Or to merge several page files into a single one. .page format is a compressed xml format. So it can be parsed by any other application. tar xvfpz your.page It cont...

Re: gphistogram have an anomalous grapfic output

Hi Luigi, I'm fine with your spac curve and the selection you did in spac2disp. Just make sure that kmin does not correspond to wavelength too large compared to your array aperture. Roughly speaking, your array has a 500 m aperture. A kmin of 0.0015 corresponds to a wavelength of 4189 m (lambda=2*pi...

Re: Output path not visible on MacOs

Hi Alex, In the GUI, you can export results inside the result sheet. For Linux and Window, it is in the top menu, "Tools" if I remember well. On Mac, you have to right click anywhere on the sheet to get an equivalent of the top menus. If you want to process more automatically, you can use geopsy-hv ...

For each inversion thread a sub-directory is created inside the working directory specified in the target options. One file 'parameter' file is created in each sub-directory. The current directory of each sub-process is set to the corresponding sub-directory. Your process must read 'parameter' in it...

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

Hi Luigi, Thanks for your reports. 1) I've just checked SPAC on 3.3.2 and it runs nicely. Is there any message in the log? Can you send a snapshot of the parameters (all tabs including rings)? There is maybe something linked to particular value. 2) If you increase kmin to something positive, the nex...
