UI Name :
Cbsi_Motion_Correction

Syntax :
function data_dc = hmrR_MotionCorrectCbsi(data_dc, mlActAuto, turnon)

Description :
Perform a correlation-based signal improvement of the concentration changes in order to correct for motion artifacts. The algorithm follows the procedure described by Cui et al.,NeuroImage, 49(4), 3039-46 (2010).

Inputs :

• data_dc: Concentration changes (it works with HbO and HbR)
• mlActAuto:
• turnon: Skip this function if turnon=1. Otherwise execute the function. Default is to execute the function if this does not exist.

Outputs :

• data_dc: dc after correlation-based signal improvement correction, the same size as dc (Channels that are not in the active ml remain unchanged).

Usage Options :

• Cbsi_Motion_Correction: dc = hmrR_MotionCorrectCbsi(dc, mlActAuto, turnon)

Default Parameters :

• turnon: 1

Prerequisites :

• Delta_OD_to_Conc: dc = hmrR_OD2Conc( dod, probe, ppf )
