This vignette provides you a simple example to construct region-level connectivity network. In example below, when the programming is running, the progress bar will be generated.

# write data into temp file. The generated NIfTI
# provide you a general structure of fMRI data.
filePath <- tempdir()
# the nii.gz fMRI imaging file is created (toy example)
oro.nifti::writeNIfTI(brainKCCA::input_img, paste(filePath, "/", "temp", sep=""))

#read fMRI data
testcase1 <- nii2RData(niiFile1 = "temp", resolution = "3mm", imgPath = filePath)
#> Reading nii files...this progress may take a long time...
