  Method = "perc.baseline", Summary.type = "mean")

Arguments

Dataframe	a GCalcium-format data frame or matrix
Trials	a single trial number or vector of trial numbers to center
Baseline.times	range of time from Baseline.frame to compute the baseline value from
Baseline.frame	a GCalcium-format data frame or matrix containing the baseline period. If frame is not specified, Dataframe is automatically used
Method	the type of centering to be used
Summary.type	the type of summary statistic to be centered by

Value

a GCalcium-format data frame with centered values

Examples

### Format data frame
df.new <- format_data(GCaMP)

### Transform into percent baseline: relative to -3s to -1s before epoc
center_trials(Dataframe = df.new, Trials = c(1, 2, 3), Baseline.times = c(-3, -1))
