Therefore max2curve of versions 2 can work without the sixth column and correctly reproduce the histograms even of files with 5 columns (4165HVTFA).
But does it also mean that the .max files produced by HVTFA can be viewed by gphistogram and gpviewmax?
Thanks

Re: max2curve in 3.5.2
Hi Marc, I too have experienced that the .max files generated by versions 3 and above with HVTFA are not yet readable by gpviewmax (as highlighted by Lega) and those by gphistogram are very unlikely. To read .max files I still have to use max2curve from Geopsy versions 2... I attach the .max file ge...

first question about Geopsy 3.5.1
Hi Marc, thanks for the new release of Geopsy! I have a first question about the H/V tool. In the H/V toolbox/processing/taper window "flat top" appears the first time I use it. Is this a new indication compared to that of previous releases (Tukey) or is it simply a setting "inherited...

Re: fundamental frequency greater than 1 Hz.
When the bedrock/reflector is at small-medium depth it is very likely that it produces an H/V peak with a frequency >1Hz which has non-anthropogenic characteristics verifiable both by the power spectrum and by the application of Ramdondec.

Re: taper window type in H/V computation
Hi Marc, now everything is clear. In fact, after sending my post, I found your answer to Luke on the same topic where you explained that with version 3, to get the same response as version 2, the window type Tukey must be used for the taper. Now, in addition, I learned that with version 2 the button...

taper window type in H/V computation
Hi Marc, while for the smoothing function in H/V computation SESAME guidelines suggest the adoption of the Konno&Ohmachi filter, there is no indication regarding the type of window for the taper (this choice is present only since version 3.0). So far I have used Konno&Ohmachi because the ado...

Re: Stacking of shots
Sorry Marc,
but in my release (3.4.2) under Waveform there is no "add signals" option (only substract signals).

Joint Inversion N/V-DC
Hi Marc,
could the use of the N/V curve in the joint inversion with DC, instead of the H/V one, be an acceptable approach for the suppression of Love waves contribution?
Thanks

objects rotation
Hi Marc,
is it possible to rotate the objects?
For example if in H/V rotate I wanted to put the frequency on the y axis how could I do it?
Thanks

Re: Stacking of shots
Hi Marc,
I want to ask you what are the steps to obtain a sum file in time domain. I tried, but the result is always a graphical window with all files to be stacked in sequence, just like with dragging and dropping.
Thanks

Re: New masw problem with Geopsy releases above 3.0
Hi Marc,
after my post last year, the problem has not arisen again. After Pourya's post and your reply, I've verified that the step count is actually set to 100. If I set it to 1 the Active FK window remains empty.

Hi Marc,
I would like to represent the HVSR time histories.
Is it possible to do this with Geopsy?
Thanks

Damping and H/V
Hi Marc, In a your work you used damping to prove that the H/V peak was natural. This is interesting because it adds to the "classic" satisfaction of the SESAME parameters to declare naturalness. In the Geopsy documentation there are indications for setting the parameters (size of the wind...
