fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): Bandpass
Bandpass -- Apply a bandpass frequency filter to input data
usage: -expr bandpass flag minfreq maxfreq
The BANDPASS function will filter out frequencies below MINFREQ and above MAXFREQ. If MINFREQ is greater than MAXFREQ, then BANDPASS acts as a notch filter to remove frequencies between MAXFREQ and MINFREQ.
The FLAG argument can be used to select filtering options.
FLAG:
- 1 - frequencies are in time axis units (i.e. TR's) (default: frequencies are Hertz)
- 2 - 2-d spatial filtering (default is temporal filtering) [not implemented yet]
