Dear FSLers,
As an additional question to that posted by Lucia -
After using FIX (option -m) to clean your data, as well as avoiding regressing out the motion parameters following this, can you also avoid regressing out CSF and white matter signal? This is usually recommended but I am not sure if it is appropriate in combination with FIX.
Also, it appears that FIX is a very good solution to dealing with noise in low-motion datasets but has it been shown to be an efficient clean up in the context of resting-state data where a lot of motion related noise is present?
i.e. does it avoid the biases in functional connectivity that you find with high-motion data? I understand that this is quite a general question but I would be very grateful for any advice/info you may have!
Thanks for your help!
