Hey Ashley,

"I found a tutorial" is not very specific, so I assume you did not find 
it on the gmsh website. And since a *.dat file can be any kind of file, 
your question is not really related to gmsh in general bur rather 
specific to the program you want to use afterwards. It looks like 
someone has written a small executable which converts the gmsh output to 
something you need for further processing with your specific program.

But you are lucky! I am a PhD student in Earth Science as well and I 
assume you want to use R3t, the geoelectrical modeling and inversion 
code by Andrew Binley!? If so, you can download the latest version from 
his website then you will find a gmsh2r3t python script that I wrote a 
few years ago. If you have a Python interpreter installed 
(www.python.org), then you can simply double-click on it and you will 
see a small GUI asking for the *.msh file. If you need any additional 
help, feel free to contact me.

Good luck
Florian

> Hello.  What you're describing seems like the behaviour I expect from Gmsh.  Why do you expect a header?  I think the operating system will know the date and time of last modification; or you could add a comment manually if it's the time of creation that's to be preserved.
