Dear Experts, I have tried several run in Melodic, changing the High pass filter cut off max 100 to 128, i used to get atleast 150 to 170 Components for normal control (2 subject). Is this right or wrong based on the volume, or if i reduce the Volume will i get lower component. eg:- 60 component. also DMN is missing , kindly need guidance. I used Resting state GE 750 W Discovery, TR.2.5. Total volume 250. -- ___________________________________________________________ Regards, *Ai* *PhD Scholar* *TUM, Munich, Germany*
