This function takes an event-related design matrix and convolves it with a specified Hemodynamic Response Function (HRF) to create a new design matrix suitable for fMRI analysis. It also supports additional arguments for flexibility and customization.

Usage

# S3 method for event_term
convolve(
  x,
  hrf,
  sampling_frame,
  drop.empty = TRUE,
  summate = TRUE,
  precision = 0.3,
  ...
)

Arguments

x

A data frame containing the input design matrix.

hrf

A Hemodynamic Response Function to convolve the design matrix with.

sampling_frame

A data frame specifying the sampling frame for the analysis.

drop.empty

Logical. If TRUE, empty rows in the design matrix will be removed.

summate

Logical. If TRUE, the convolved design matrix will be summed.

precision

Numeric. The desired precision for the calculations.

...

Additional arguments to be passed to the function.

Value

A convolved design matrix, in tibble format.
