do_QC: Mask out invalid data

In hrf: Hemodynamic Response Function

Mask out invalid data

Description

Mask out data locations that are invalid (missing data, low mean, or low variance) for any session.

Usage

do_QC(BOLD, meanTol = 1e-06, varTol = 1e-06, verbose = TRUE)

Arguments

BOLD	A session-length list of T \times V numeric BOLD data.
meanTol, varTol	Tolerance for mean and variance of each data location. Locations which do not meet these thresholds are masked out of the analysis. Defaults: 1e-6.
verbose	Print messages counting how many locations are removed? Default: TRUE.

Value

A logical vector indicating locations that are valid across all sessions.

Examples

nT <- 30
nV <- 400
BOLD1 <- matrix(rnorm(nT*nV), nrow=nT)
BOLD1[,seq(30,50)] <- NA
BOLD2 <- matrix(rnorm(nT*nV), nrow=nT)
BOLD2[,65] <- BOLD2[,65] / 1e10
BOLD <- list(sess1=BOLD1, sess2=BOLD2)
do_QC(BOLD)
