Filter in time
bandpass_4dfp
Independent specification of low and high ends; remove linear trends; remove DC
Usage: bandpass_4dfp <(4dfp|conc) input> <TR_vol>
Examples:
bandpass_4dfp qst1_b1_rmsp_dbnd_xr3d[.4dfp.img] 2.36 -bl0.01 -ol1 -bh0.15 -oh2
Options
-b[l|h]<flt> |
specify low end or high end half frequency in hz |
-o[l|h]<int> |
specify low end or high end Butterworth filter order |
-n<int> |
specify number of pre-functional frames (default = 0) |
-I<int> |
specify interpolation mode (0 = none; 1 = linear; 2 = cubic spline) (default = 1) |
-f<string> |
specify frames-to-count format (overrides option -n) |
-F<string> |
read frames-to-count format from specified file (overrides options -n and -f) |
-t<str> |
change output filename trailer (default=”_bpss”) |
-a |
retain DC (constant) component |
-r |
retain linear trend |
-E |
code undefined voxels as 1.e-37 |
-M |
disable undefined mask computation |
-B |
compute gain using correct Butterworth formula (default squared Butterworth gain) |
-@<b|l> |
output big or little endian (default input endian) |
N.B.: undefined values are zero, NaN, or 1.e-37 N.B.: input conc files must have extension “conc” N.B.: omitting low end order specification disables high pass component N.B.: omitting high end order specification disables low pass component
