You can ignore this. This probably because IDEA does not know about the 
oversampling in ODIN...

There are two possibilities in ODIN for averaging:
1) Use the reco index 'average' to average the complex signal data before 
reconstruction. Please refer to the odinonep.cpp sequence how to do this.
2) Sum up the reconstructed repetitions yourself (Use the -sp switch of 
odinreco to store the phase) or use the "repcoll | repsum" functors of Odin 
(cf. tj_verve.cpp sequence).
