I'm preparing a paper to send my first paper to one of the Elsevier journals, I designed a new approach to identify the Balloon hemodynamic model
(Friston 2000). I want to calibrate the model using real fMRI measurement (a simple fMRI blocked design = begin and stop finger tapping every 30 s),
1) Start FSLeyes
2) Open the "filtered_func_data.nii.gz" and "thresh_zstat1.nii.gz".
3) View > Time series.
Two signals appear:
filtered_func_data.
filtered_func_data (Full model fit).
Is this the right way to extract the real "BOLD" signal from a voxel and which of the two signal should I use?
