Non ho capito se hai problemi con max 2curve o è il modulo implementato sul geopsy che non funziona.
Puoi allegare la registrazione e provo a farti il file .max

I did not understand if you have problems with max 2curve or the module implemented on geopsy that does not work.
You can attach the recording and try to make the file. Max

attached there is the file with REMI registration.
my first problem is that the output file of the f-k passive tool contains only #lines and no data.
the investigation site is 300 m apart from the nearest street with traffic

questo è il file grazie per l'aiuto, io sono a Pisa
il primo problema è che l'uscita di f-k passive è un file senza dati al termine delle linee con #
Il sito è distante circa 300 m da strade trafficate

Ho visto i tuoi dati.
Penso che il problema fosse il To di alcuni segnali (canale 24). Ti invio una cartella con il file riassuntivo ed una elaborazione .max:
distanza geof. 4m, freq dep 15T, no antitriggering, kmin 0,032, kmax 1,57, v min 50 m/s,
band width 0,10, maximum number 3

Ti consiglio di allungare i tempi di registrazione (almeno 1 minuto x 10 registrazioni)

I saw your information.
I think the problem was the To some signals (24). I am sending you a folder with the file summary and elaboration. max:
I suggest you extend the recording time (at least 1 minute x 10 recordings)

Thanks for the double language posts. Effectively, if the .max is empty or contains only comment lines (#), there was not enough recorded time to place at least one window. Either increase the recording time as suggested by massimo, decrease the length of time windows or increase the frequency.

Fixing the T0 also helps to process all signals you recorded. If you drag all your signal to a chronogram (4th viewer in the toolbar after map), you can see green ranges where your signals are available, red ones when noting is available and blue ones when there is overlap. In case of overlap, Geopsy cannot insert a time window, hence drop both recordings.
