From Hans:

The people working on dual phase TPC's were able to get the full chain running and I think everything can be found in the dune repositories. I have attached the fcl and gdml file they used.

I am in the process of compiling an example that shows how to use the new workflow using a simplified liquid Argon Detector geometry. But I still have to complete some coding which completely splits the electron drift and detector response. That means the larsim:source:larsim/ElectronDrift/SimDriftElectrons_module.cc used by the example above will be split into the DriftElectronstoPlane_module.cc and another module that produces the simchannels.

Here the DriftElectronstoPlane_module will take the SimEnergyDeposits as input, drift the electrons to a surface and create the SimDriftedElectronClusters which then are the input for a new module that takes the SimDriftedElectronClusters as input and simchannels as output.

Hans, can you take care of this?

Currently an example is available as part of dunetpc. It was developed by the group working on a dual-phase TPC (Jose, Bea and Paul). So to look at the example one needs to setup dunetpc. Below is what I am doing until we find a place for a more generic example.

mkdir example 
cd example
mkdir larsim_dev
cd larsim_dev
source /cvmfs/fermilab.opensciencegrid.org/products/larsoft/setup
setup mrb
export MRB_PROJECT=larsim
mrb newDev -v v08_07_00 -q e17:prof
source localProducts_larsim_v08_07_00_e17_prof/setup
cd srcs
mrb g larsim
cd $MRB_BUILDDIR
mrbsetenv
mrb b -j 4
unsetup cetpkgsupport
source /cvmfs/dune.opensciencegrid.org/products/dune/setup_dune.sh
setup dunetpc -qe17:prof v08_20_00 
wget https://cdcvs.fnal.gov/redmine/attachments/download/53755/fcl.tgz
tar xzvf fcl.tgz
lar -c dune_refactored.fcl

to run the module by Bill seligman which does the simdrift and injects the charge into the simchannels. (Currently this still depends on the LArG4Parameters service but we will remove this dependency)

lar -c dune_refactored2.fcl

I took Gianluca's larcorealg:source:larcorealg/Geometry/gdml/MinimalLArTPCdetector_nowires.gdml file and modified it. The gdml file is attached.

Now everything is square as Gianluca intended. The gdml as well as some screenshots are attached. I am not quite done yet but the gdml file should be quite compact and easy to read and modify.
