fMRIscrub is a collection of routines for data-driven
scrubbing (projection scrubbing and DVARS), motion scrubbing, and other
fMRI denoising strategies such as anatomical CompCor, detrending, and
nuisance regression. Projection scrubbing is also applicable to other
outlier detection tasks involving high-dimensional data.
You can install the development version of fMRIscrub from GitHub with:
# install.packages("devtools")
devtools::install_github("mandymejia/fMRIscrub")s_Dat1 <- scrub(Dat1)
plot(s_Dat1)
Dat1_cleaned <- Dat1[!s_Dat1$outlier_flag,]Two scans from the ABIDE
I are included in fMRIscrub: Dat1 has many
artifacts whereas Dat2 has few visible artifacts. Both are
vectorized sagittal slices stored as numeric matrices. They are loaded
into the environment upon loading the package.
We acknowledge the corresponding funding for the ABIDE I data:
Primary support for the work by Adriana Di Martino was provided by the (NIMH K23MH087770) and the Leon Levy Foundation. Primary support for the work by Michael P. Milham and the INDI team was provided by gifts from Joseph P. Healy and the Stavros Niarchos Foundation to the Child Mind Institute, as well as by an NIMH award to MPM ( NIMH R03MH096321).
