Dear all,

I used the Matlab script outputfile_converter.m to convert output into DZT format, but when I selected the outputfile, an error popped up:

Error using h5readc

Unable to open file. Filename may be corrupt or have unsupported characters.

Error in h5read (line 58)

[data, var_class] = h5readc(Filename,Dataset,start,count,stride);

Anyone encounter the same issue like me? My file name is 'trial.out' so I think it is supposed to be fine. Thankyou.

Hello Beth,

Just put your gprMax .out file in the same folder with the script.

Kind regards,

Dimitris

Dear Dimitris,

After I choose the type of file to be converted, an error poped up:

Error in outputfile_converter (line348)

HDR.antenna = pad (HDR.antenna, 14, 'right');

Although there is a window pop up showing the file is exporting, it seems to be frozen. what should I do?

Best Regards,

Beth

Dear Beth,

I dont have any issues with the script. The error is probably due to a different Matlab version.

Can you provide me some info about your Matlab version?

Hi Beth,

Can you attach the output file you experiencing problems with.

Kind regards,

Hi Beth,

I tested both your output files with the converter script, and both worked OK for me (MATLAB R2018a). I suspect, as Dimitris indicated, it is something subtle with the version of MATLAB you are using. Can you copy/paste the exact error message you are getting.

Thanks,

Craig

Dear Craig,

I really appreciate your help. Here are the error I have:

Warning: Default string does not match any button string name.

Undefined function or variable 'pad'.

Error in outputfile_converter (line 348)

HDR.antenna = pad(HDR.antenna, 14, 'right');

Best Regards,

Beth

Hi Beth,

So your version of MATLAB (R2016a), does not have support for a lot of string functions. One of those is the pad function which the script uses. I have made a quick modification to the script which should workaround the problem for you. If you pull the latest version of gprMax from GitHub you'll get the updated script.

Kind regards,

Craig

Dear gprMax developers, I am using gprMAX (I'm a new user). I was wondering where I can find that script that you mention, It will definitely help me a lot in my project. This is my email to get in touch: moises....@gmail.com

You will find the 'outputfile_converter.m' script in the tools->MATLAB_scripts folder of the gprMax package.
