6 motion regressors output

Submitted by Helen Sawaya on Fri, 07/12/2013 - 19:30

 Dear experts,

I am running only motion regression in DPARSFA and looking at the output it appears that the image is demeaned. Does it not output the functional image with the mean added back in order to use it for further processing?

Thank you
Helen

No. Adding mean back or not doesn't affect any results of filtering, ALFF, ReHo, FC, etc.
You need to use code for that kind of analysis (adding mean back).

 Thank you for your reply. I thought I got bizarre results after running functional connectivity using the demeaned image after motion correction. I will try it again and see what results.

Thanks again!
Helen
