Load and threshold coefficient maps

Source: R/plot_helpers.R
load_and_mask_coef.Rd

Loads a vertex-wise coefficient map from a specified results directory and generates a significance mask based on a threshold method (e.g., Cluster-Wise Significance, FDR, uncorrected p-values, or an absolute numeric threshold).

Usage

load_and_mask_coef(hemi, measure, stack, res_dir, threshold)

Arguments

hemi

Hemisphere identifier ("lh" or "rh").

measure

The morphological measure (e.g., "thickness", "area").

stack

The stack or contrast identifier.

res_dir

Path to the directory containing the .mgh results files.

threshold

The threshold criteria. Can be "cws" for cluster-wise significance, a string expression like "fdr < 0.05" or "p < 0.01", a numeric absolute value, or NULL for no thresholding.

Value

A named list containing:

  • coef: The numeric vector of loaded coefficients.

  • mask: A logical vector indicating significant vertices, or NULL.
