data_wrangling: data_wrangling

In epongpipat/ppi: Psychophysiological Interaction (PPI)

data_wrangling

Description

uber data wrangling wrapper function to create data for each step of data wrangling for each psy, phys, and ppi variables to ultimately create the design matrix. This function is a wrapper of create_hrf_afni(), create_psy_var(), create_phys_var(), create_ppi_var(), and create_design_matrix()

Usage

data_wrangling(
  psy_events_data,
  psy_unlabeled_trial_type,
  psy_contrast_table,
  phys_data,
  detrend_factor,
  hrf,
  tr,
  n_volumes,
  upsample_factor = NULL,
  deconvolve = TRUE,
  nuisance_var = NULL,
  afni_path = NULL,
  afni_quiet = FALSE
)

Arguments

psy_events_data	events data with columns of onset, duration, and trial_type
psy_contrast_table	contrast code
phys_data	time series data of physiological variable (seed ROI)
detrend_factor	factor to detrend time series
hrf	hemodynamic response function time series data for convolution and deconvolution step
tr	repition time (tr) in seconds
n_volumes	number of volumes or time points
upsample_factor	factor to upsample psy and phys data for convolution and deconvolution step (default: NULL)
deconvolve	perform deconvolution of phys and convolve of ppi term (also known as deconvolve-convolve or reconvolve step) (default: TRUE)
nuisance_var	data of nuisance variables to include in design matrix (default: NULL)
afni_path	path to afni directory (default: NULL)
