You have to add the vector to the appropriate loop (via the [...] operator 
while building the sequence). For automatic reconstruction, you also have to 
inform the EPI Readout about this vector, using 
epiadc.set_reco_vector(average, vector)

Only the indices of the enum 'recoDim' up to the index 'templtype' are 
available to sequence programming, the others are only used internally in 
odinreco. The 'repetition' index is set automatically for all parts of the 
sequence which are repeated unchanged.

In any case, it should not segfault. Please send me the code to my private 
Email adress (th...@jo...) and I will look into it. Probably some 
missing range checking...

You do not have to specify an explicit repetition vector/index, just repeat 
part of the sequence (as mentioned above).
