Hi,
upon readout using HPS2014ReadoutToLcio.lcsim as 
steering file (HPSTracker2014-v0 geometry) I get a bunch of messages:

Apr 23, 2015 11:37:17 PM org.hps.recon.ecal.cluster.ClusterDriver process
SEVERE: The input hit collection EcalCorrectedHits is missing from the 
event.

... should I worry?
thanks, cheers
     Alessandra
