dct_convert: Convert between number of DCT bases and Hz of highpass filter
In neuroconductor/fMRIscrub: Scrubbing and Other Data Cleaning Routines for fMRI
Description
Usage
Arguments
Details
Value
Description
Provide either n or f to calculate the other.
Usage
1
dct_convert(T_, TR, n = NULL, f = NULL)
Arguments
T_
Length of timeseries (number of timepoints)
TR
TR of the fMRI scan, in seconds (the time between timepoints)
n
Number of cosine bases
f
Hz of highpass filter
Details
If only the total length of the scan is known, you can set that to TR
and use T_=1.
f = n / (2 * T_ * TR)
Value
If n was provided, the highpass filter cutoff (Hz) is returned.
Otherwise, if f was provided, the number of cosine bases is returned.
The result should be rounded before passing to dct_bases
