Dear SPM users,
my fMRI data come from a 7Tesla recording system with TR=57 ms and TE=26 ms,
which, as far as I know, have an influence on the factors (k1,k2,k3,V0) of the BOLD signal,
which are part of the Balloon model for the DCM analysis.
I know that I have to change the parameters at spm_gx_fmri.
Does anyone know what values I should set?
Is there a paper I can refer to?
Best,
Foteini.
