[gmx-users] Where in the source code is the .edr file written?

[Andrew DeYoung]

Hi,

I am running Gromacs 4.5.5.  Can you please tell me what source code file(s)
contain the code for writing the .edr file during mdrun?  The manual gives a
lot of information about how various quantities (e.g., pressure) are
calculated, but I would like to see exactly in the code where quantities
like density and pressure are computed and are written to the .edr file.  I
am not sure how straightforward this will be, but I just wanted to ask if
you could point me in a general direction in the source code.

Thanks so much!
