Hi there,

I'm relatively new to Featquery and just wanted to verify how to interpret the % signal change of a Parameter estimate.

Is the % signal change the percentage of total voxels within a specific ROI which show activation within the particular cope (i.e. the cope from task > rest)

OR

Is the % signal change just the average of the signal change within the ROI for task > rest, irrespective of the number of total voxels within the ROI?

If someone could clarify, that would be great.

Also, if it is indeed the second option, is there a way to get the % signal change as a function of the number of voxels within a given ROI?

thanks!!

Corinna
