" you normally do en route to making your final `resting state time\n"

"\n"
"* fbot = lowest frequency in the passband, in Hz\n"
" ++ fbot can be 0 if you want to do a lowpass filter only;\n"
" HOWEVER, the mean and Nyquist freq are always removed.\n"
"\n"
"* ftop = highest frequency in the passband (must be > fbot)\n"
" ++ if ftop > Nyquist freq, then it's a highpass filter only.\n"
"\n"
"* Set fbot=0 and ftop=99999 to do an 'allpass' filter.\n"
" ++ Except for removal of the 0 and Nyquist frequencies, that is.\n"

" ++ You could use 3dRSFC followed by 3dcalc to get the same effect.\n"

" you can still get Fine StatisticaL maps.\n"

"* The actual FFT length used will be printed, and may be larger\n"

" each of these: 3, 9, 27, and 5, 25, 125).\n"

"* Note that the results of combining 3dDetrend and 3dRSFC will\n"
" depend on the order in which you run these programs. That's why\n"

" time series filtering can be done properly, in one place.\n"

"* The output dataset is stored in float format.\n"

" done only to exclude the time series mean and the Nyquist frequency:\n"
" (0) Check time series for initial transients [does not alter data]\n"
