This isn't related to FSL - but I am desperate and thought some of the members here would be able to assist.
I have ran analysis on my functional MRI data using a script provided by somebody else. Problem is, I am not entirely sure what the output is.
The numbers I have for the ROIs should be representing 'Response Magnitude'. However, there are some negative numbers. I was under the impression that a negative magnitude doesn't exist, and I am confused as to how this should be interpreted.
Any help would be seriously appreciated.
