Temporal filtering question

Hi Alfonso,

I have a question about the temporal filtering processs in Conn. I read on the forum that Conn uses Fast Fourier Transformation (FFT) to bandpass filter the data. Is this correct? Also, is it the same as the original method from Biswal 1995 and Uddin 2009? I believe they used this, "temporal bandpass filtering (highpass temporal filtering: Gaussian-weighted least-squares straight line fitting, with sigma=100.0s; Gaussian lowpass temporal filtering HWHM 2.8s)"

Thanks for your help.

Best wishes,
Mike
