New masw problem with Geopsy releases above 3.0

[luigiV]

Hi Marc, I'm working with Masw FK and after a first run where the FK results are correct for different time windows and offsets, the FK results no longer appear and the window remains empty without any error being highlighted in the message window, rather than the operation was completed.
I reloaded Geopsy 3.4.2 and also 3.3.6 having the foresight of clear the tools from Geopsyland, but to no avail. Obviously I tried with previous processed files too and and even with these it was not possible to obtain the FK spectrum.
Using an older version (2.10) the tool works.
This is the first time it has happened and I don't understand the reason.
What is your opinion?

thank you
Luigi

Hi mark,

the same thing is happening to me. The F-K method is not showing the colored dispersion image. Any idea what could be wrong? It worked for me in the morning but suddenly it is not showing anything ( the log does not show any error).

Hi,

I've no idea. I checked with 3.4.2 without being able to reproduce the problem. Can you check if the opacity of the layer with the FK results is at 1 (in graphic properties)? Can you copy the text of the complete log and post it here?
That's the first step. In a second step, I will ask you to send me a signal file, to further inquire about this issue.

Best regards,
Marc

Hi Mike,

The opacity is 1 as you can see in the attached screenshot. Also, it does not matter which file I am using, I do not get any results. Here is the complete log :

I think that I found the problem. Can you try to switch to "step count" for velocity sampling? The number of steps is probably 1. Set for instance 100. Is it better?
It occurs when switching to linear scale for velocity. After closing the tool and re-opening it, the number of samples is not properly initialized.
This is fixed for the next release (3.5.0).

Thank You Marc. You saved me --- It is working now.

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.

Thanks for your returns. The next release is now more robust on this aspect. 3.5.0-preview is available from git (compilation required under Linux or Mac). Binaries for Windows will probably follow within a week or two.
