Dear Experts,

I recently discovered the rs-HRF toolbox for estimating and modeling the resting-state HRF from resting-state fMRI data.

I have successfully installed rs-HRF on SPM in MATLAB and followed the tutorials and documentation. However, I couldn't find clear instructions on estimating the HRF from .mat files containing preprocessed time series for each ROI.

Could you please clarify which option I should select in the GUI (Voxels, ROI volume, Signals, Vertices, etc.) to estimate the HRF from my ROI time series?

Your guidance would be greatly appreciated.

Best regards,

Abir.
