[VoxBo] rfx analysis

[marina bedny]

Hello,

FYI
When creating rfx tes files vbprep does not skip over covariates of  
no interest in applying the contrast vector. So if you happened to  
add your covariates of no interest first for some subject, the order  
of the contrast vector will not be right for these subjects. Most  
people probably know this already, but I thought the info may be  
useful for someone.
