The temporal resolution of the data, i.e. the time between volumes,
in seconds. |
hpf |
The frequency at which to apply a highpass filter to the data
during pre-processing, in Hertz. Default: The highpass filter serves to detrend the data, since low-frequency variance is associated with noise. Highpass filtering is accomplished by nuisance regression of discrete cosine transform (DCT) bases. Note the |
GSR |
Center BOLD across columns (each image)? This
is equivalent to performing global signal regression. Default:

Q2 , Q2_max |
Obtain dual regression estimates after denoising? Denoising is based on modeling and removing nuisance ICs. It may result in a cleaner estimate for smaller datasets, but it may be unnecessary (and time-consuming) for larger datasets. Set If |

Tolerance for variance of each data location. For each scan,
locations which do not meet this threshold are masked out of the analysis.
Default: |
maskTol |
Tolerance for number of locations masked out due to low
variance or missing values. If more than this many locations are masked out,
this subject is skipped without calculating dual regression. If |
