Hello Norman,

I uploaded some files to the JLab servers. You can find a hodoscope readout
file at:

/work/hallb/hps/mccaky/hodoscope_2pt3_466-readout.slcio

and a recon file at:

/work/hallb/hps/mccaky/hodoscope_2pt3_466-recon.slcio

The recon file should be reproducible by using the standard Monte Carlo
reconstruction file, and produces the error I mentioned when trying to
access the calorimeter track state. You need to use iss166 to access these
files, though, since they use a detector geometry that is not presently in
the trunk.

Thanks,

Kyle
