In UNCDEPENdLab/fmri.pipeline: Analysis of fMRI Data on HPC clusters

Interpolate an aligned fmri_ts object onto a consistent time grid with respect to a target event

Description

Interpolate an aligned fmri_ts object onto a consistent time grid with respect to a target event

Usage

interpolate_fmri_epochs(
  a_obj,
  evt_time = "evt_time",
  time_before = -3,
  time_after = 3,
  output_resolution = 1,
  group_by = NULL,
  time_audit = FALSE
)

Arguments

a_obj	an fmri_ts object that has data aligned to an event of interest
evt_time	column name in a_obj event data to which time series should be aligned and interpolated
time_before	The earliest time point (in seconds) relative to the event to be output in interpolation
time_after	The latest time point (in seconds) relative to the event to be output in interpolation
output_resolution	The timestep (in seconds) used for interpolation
group_by	a character vector of keying variables used for aggregation of data prior to interpolation
time_audit	If TRUE, additional columns will be added to the output showing how alignment is calculated vis-a-vis event timing
