Dear Prof. Henson
I have a question relative to the formula to approximate the BOLD latency in Henson et al 2002 : 2C/(1 + exp(Dβ2/β1)) − C (where C = 1.78, D = 3.10)
In one of your previous post (https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind0911&L=spm&P=R105459&1=spm&9=A&J=on&d=No+Match%3BMatch%3BMatches&z=4) , you tell that McLaren has found a problem in this sigmoidal equation due to SPM update.
I can't found this McLaren post (dead link).
Can you explain me how can I found the correct formula and constants to work with SPM12 (and data recorded on a 3T scanner).
Thank you very much
Michael
