Hello AFNI gurus - quick question for you.

I am covarying my seed-based connectivity imaging results by genotype status, in this case by # of base pairs (i.e., a continuous variable, with range from n to n + some much larger bp number). When I am reading the imaging outpt, some areas demonstrate more connectivity, others less etc etc.

When I see an area has increased connectivity, what is the correct way to interpret these results? Higher base pairs are associated with increased connectivity? Same thing with areas with reduced connectivity? My guess is that the outpt is linear, ie that higher numbers of the covariate predicts more changes etc., but that remains a guess.

Thanks for your help!
