Module: reconst/frf

Compute a Fiber Response Function (FRF) from a DWI. Note that multiple types of FRF are available through the method argument. The single-shell single-tissue (ssst) FRF is performed by choosing the ssst method (task.ext.method). This is expected to output a single WM FRF. The multi-shell multi-tissue (msmt) FRF is performed by choosing the msmt method (task.ext.method). This is expected to output a WM FRF, a GM FRF and a CSF FRF, each containing values for every shells.
