Hello,
I'm using featquery to extract % signal change from each of my subjects using
anatomical ROIs and a cope image. I have two questions:
1. Some of my subjects are showing a negative percent signal change. I am
concerned that outliers may be causing this (atleast in part). Is there any
easy way to check whether this may be the case?
2. If I apply a threshold of "0", does this mean that, foreach timepoint where
% signal change is calculated to be negative, the % signal change is set
to "0"?
many thanks in advance for the help!
