[Homer-users] Multiple subjects averaging (ROI)

[Felix Le]

Hi, 
 
I'm trying to average the ROI of each of my subjects within HOMer. Every subject represents one session. Whenever I try to open a 3rd session (3rd subject), HOMer gives me an error :
 
Operands to the || and && operators must be convertible to logical scalar values.
 
Does this ring a bell to anyone ? 
 
Thank you, 
 
Felix
