[Halla12_software] ec_solid_gemc as an example

[Richard S. Holmes]

Let me make sure I understand what's happening here. Are the various .txt
files outputs of the .pl scripts? What writes
solid_PVDIS_ec_forwardangle__parameters_Original.txt? Or is that an input?
Is that read by solid_PVDIS_ec_forwardangle_real.pl which then
outputs solid_PVDIS_ec_forwardangle__geometry_Original.txt? I think that's
what your slides are saying, is that right?

So if one wants to change the EC configuration one edits
solid_PVDIS_ec_forwardangle__parameters_Original.txt, but to change the
materials or bank definition you have to edit the Perl script?

I like that in the bank definition there is a description of each field.
However, I would urge that the description should include the units. Or
there should be a separate column for units.

This bothers me:

solid_ec_bank.pl defines output bank "solid_ec", it needs to exactly match

Isn't this exactly the sort of thing we're trying to avoid? Having
definitions of things in multiple places all of which have to be in synch
for it to work?

What about the digitization, calibration, and analysis software? Presumably
they don't read solid_PVDIS_ec_forwardangle__geometry_Original.txt since
that's a GEANT-focused description; instead do they
read solid_PVDIS_ec_forwardangle__parameters_Original.txt? And the other
.txt files?
