Dear Zach,
Did you use the effect script directly or try to interface it with
Featquery in some fashion? The raw values from the script, by the way, are
simply the adjusted parameter estimates (which scale according to the
intensity values from your scanner) so these need to be divided by the mean
signal intensity of your ROI over the time series. Depending on the
version of the script you're using, this may be the last column of values
in the output. If you multiply the result by 100, you should get % signal
change (ranging from 0-100%).
Another thing to look out for is that the script is written to use PE
values. If you change it to use contrast images or zstats or anything like
that, the values will be incorrect.
Do any of these sound familiar? If not, we'll probably need some more
details on this one.
Cheers,
Joe
