Lowfreq -- Remove slow temporal fluctuations (detrend)

usage: -lowfreq nnodes flag

For DETRENDING, a smooth curve is generated for each pixel timecourse as a cubic spline interpolation through NNODES points. The nodes are uniformly spaced along the timecourse; their values are calculated piecewise based on the FLAG argument.

  • FLAG -
    • 0 - mean
    • 1 - median
    • 2 - midpoint of least squares fit
