Hi Mikhail and Chuck,
For developing the area detector det xface I created a jungfrau xtc2 file using Eliseo’s translation scripts:
~cpo/git/lcls2/psana/psana/dgramPort/jungfrau.xtc2

Instructions for running his translator are on this page:
https://github.com/slac-lcls/lcls2/tree/master/psana/psana/dgramPort

The python script below dumps configuration information and event data.  I think the two goals should be:
- have the script below be able to call a psalg C++ det.calib (via cython?)
- the drp be able to use the psalg C++ as well

from psana import DataSource
ds = DataSource('jungfrau.xtc2')
run = next(ds.runs())
dg_cfg = run.configs[0]
print('Found cfg version',dg_cfg.software.myjungfrau.cfg.version)
print('Found raw version',dg_cfg.software.myjungfrau.raw.version)
print('Config number of pixels:',dg_cfg.myjungfrau.cfg.numPixels)
for evt in ds.events():
    dg = evt._dgrams[0]
    print(dg.myjungfrau.raw.frame.shape)

- the drp be able

Thinking about it, I think the way to start might be for me to give
 you some C++ code that “simulates” what the drp will give you: a 
configure datagram and event data.  I think Chuck and I did this with 
the HSD.
After this “drp” version works,  we think about the python wrapping, I guess.
