Hi all,
I have run some pilot scans with a resting state experiment and tACS stimulation.
Unfortunately I had to change the timing in some of the scans so that subjects already did a rating during the last 23 volumes of the scan and I do not want to include these volumes in my analysis.
Is there a way with fslmaths to delete the same amount of volumes at the end of the scan so that I can still compare between subjects or would it be better to use confound EVs?
Many thanks
christiane
