Dear DCM experts,
I would like to implement my own models (with regard to task-rest
interactions) within the DCM framework. My questions are:
Which hemodynamic model should I use? Would you recommend to simply use
the newest model, e.g. as implemented in spm_fx_fmri.m and spm_gx_fmri.m?
I want to study the effect of several external variables on one region.
I have some parameters to optimize describing the external variables and
their influence on the region. Can I use spm_nlsi_GN.m (e.g. the
implemented EM with free energy as fitness-function) as it is for my
models or do I have to change something?
Thank you,
Martin
