Inverse Logit Hemodynamic Response Estimation Toolbox
This toolbox will estimate parameters for a flexible hemodynamic response function (HRF) using three superimposed inverse logit functions. The HRF is fit using seven parameters, and can capture a variety of HRF shapes, including sustained activations.
Main inputs include a data timeseries and indicator (stick) function for the onsets of events.
The function can be used with ROI timeseries or incorporated into whole-brain HRF-estimation tools.
