Re: [Freesurfer] low eff and VRF values

You're getting very low VRFs because of the sub-TR estimation (TR=1.5, but TER=0.5), so you reduce your power to about 1/3. This is not a problem unless you analyze your data using an FIR. If you assume a shape, then the power will come back. doug On 05/15/2012 11:41 AM, Andrew Valdespino wrote
