How to save dinver best fitting models as ascii files?

Hey guys, I checked previous posts on a similar topic with the usage of gpdcreport command to extract dinver best fitting models from those report files. If I just use "gpdcreport run_01.report -pm" , I'll get lines of text on my screen. Could anyone tell me how the gpdcreport output is organized? I...

Problems with installing geopsy package in Ubuntu (11.10).

Hey guys, I need to install geopsy on a new Linux workstation that is running Ubuntu 11.10. I thought that I've got all of the components ready, and the configuration step went through without troubles. However, when I run the makefile, the compilation always fails at the very beginning -- It failed...

Re: Questions regarding time picking in graphic signal viewe

Thank you very much! These tricks are tremendously helpful! A semi-automatic picking functionality would be great to have! A control solely based on my mouse clicking often gives me the feeling of -- Hmmm, I did not click right on that zero line, or, oops, my picking deviates from the peak/trough I ...

Is there a way to do interactive fk-filtering in geopsy?

Hey guys,

Is interactive fk-filtering (or non-interactive one) a doable operation in geopsy? If so, could anyone point me to the corresponding manual pages? Thank you very much!!! :)

Questions about time range settings for linear fk analysis.

Hey guys, I am trying to apply a varying time window on time series that are used for surface wave dispersion analysis. The ideal operations in my head would be to have a window with fixed duration T and different starting time t0. t0 can be arrival time of Rayleigh wave for each signal, or any othe...

Questions regarding time picking in graphic signal viewer.

Hey guys, I have a couple of questions about time picking in graphic signal viewer: (1) About the pop-up window asking me to "Open an existing make-up": I am trying to do some first arrival time pickings in the graphic viewer. To change "active signal", I followed the manual instruction by pressing ...

Re: Spikes present in time series displayed in graphic viewe

Sure! The SEGY file is of 2.5 MB, which is too large to be posted on this forum. I used email address to send you a tar.gz file. Is the email address correct? Thank you very much! :)

Spikes present in time series displayed in graphic viewer.

Hey Guys, When I loaded my SEGY files in geopsy graphic window, some traces look perfectly fine while others have spikes present at the beginning of the time series. However, these time series look normal (i.e. no spikes present) when I checked these time series in matlab or other seismic data viewe...

Re: Questions about suitable data format for MASW analysis.

After multiplying the SAC files by a factor of 1.0e+19 (Does not have to be this number, but I tried to get the resulting amplitudes have min/max close to -1.0/1.0), the spike is no longer there. However, I ran into another problem here -- Somehow signals displayed in my geopsy graphic window are no...

Re: Questions about suitable data format for MASW analysis.

geopsy_SACwaveforms_demo.jpg Thank you very much for the help! Sorry for getting back to this so late. Indeed, it is because the receiver coordinates needed to be corrected. After manually doing the editing in the table, now I can get dispersion curves. However, I have one more questions. My SAC fo...

Questions about suitable data format for MASW analysis.

Dear all, I am a newbie on geopsy, so this is a fairly low-tech question. I got the package successfully installed on my Linux workstation yesterday, but today I keep struggling with my own improper input data format. I used a group of SAC files as inputs for linear f-k analysis. I can visualize wav...
