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? If I want to extract Vp, Vs and density information, what am I supposed to do?
Thank you very much!

Hi,
Here are a few hints to use gpdcreport
'-pm' gives you the raw parameter values in an order that depends upon your parameterization. '-gm' or no option will export models with four columns, one line per layer: thickness (m), Vp (m/s), Vs (m/s), density (kg/m3). The first line is the total number of layers including the bottom half-space.
To get the best model (with the lowest misfit):
See -help comments about option '-best' for details. You can convert this model to a Vp or Vs curve versus depth with:
Code: Select all
gpdcreport run_01.report -best 1 | gprofile -vs

In a terminal... under Linux, Mac or by installing MSYS under Windows. You can search this forum about MSYS, there is a post that provide more details about it

Yes, it is
Dinver is directly writing the generated models into a binary file with extension .report. If you saved your dinver environment you certainly found a *_report directory at the same location as your .dinver file. This directory contains all .report files generated during your last session. If you did not save your dinver environment, there is .dinvertemp directory in your home directory ("My documents" or something like that under Windows) which contains the .report files.
As mentioned above in this topic, inside MSYS, run the following command (after "cd" to the correct directory):
gpdcreport run_01.report -best 20 > list_of_20_best_models

Just type your commands. This is shell programming. There are a lot of books about it and you can find a lot of information with your favorite search engine.

Sir,
I have got the result..sir, i want to know what "9" indicating (in attachment)?? is it showing parameters at 9 different depths.. I think
1st column - Depths
2nd column- p-wave velocity
3rd column-s-wave velocity
4th column- Density
Am i right??? I am little bit confused..about the format of result..how can i reduce the digit after fraction?? One thing i want to know that how can i copy the model parameters into a text files???

Yes, you're right
The first line indicates the number of layers including the half-space. More details about the format is provided by
To reduce the number of digits you can use awk utility like this:
Code: Select all
gpdcreportrun_01.report -best 5 | awk '
/^#/{print}
!/^#/{
if(NF>1) {
for(i=1;i<=NF;i++) printf("%.2f ", $i);
printf("\n")
} else {
print
}
}'
To export all output to a text file, you can use redirections ('>'):
Code: Select all
gpdcreportrun_01.report -best 5 > toto.txt

Thank you sir...
Another problem i am facing..I have installed full geopsy software..I am not getting gpdc tool...I need this tool for forward computation...Only some limited tool is available...I have attached a screen shot of the tools available...

gpdc is not a graphic tool. All the available tools are located in C:\Program Files\Geopsy.org\bin (under Windows if you select the default path for installation). The command line tools can be run from a MS-DOS console or better from MSYS. Linux and Mac OS X can run them from any terminal.
The PATH variable must be properly set up as explained at
