Description

This class contains meta information for surface-based data for the GIFTI data format

Slots

info

the underlying gifti object returned by readgii

Examples

# First create a SurfaceDataMetaInfo parent object
meta_info <- new("SurfaceDataMetaInfo",
                 header_file = "rscan01_lh.gii",
                 data_file = "rscan01_lh.gii",
                 file_descriptor = new("FileFormat"),
                 node_count = 40000L,
                 nels = 1L,
                 label = "thickness")

# Use the example file included in the package
example_gii_file <- system.file("extdata", "rscan01_lh.gii", package = "neurostyle")

if (file.exists(example_gii_file) && requireNamespace("gifti", quietly = TRUE)) {
  # Load the actual GIFTI file
  gifti_obj <- gifti::readgii(example_gii_file)

  # Create GIFTISurfaceDataMetaInfo object with the real file
  gifti_data_meta <- new("GIFTISurfaceDataMetaInfo",
                        header_file = meta_info@header_file,
                        data_file = meta_info@data_file,
                        file_descriptor = meta_info@file_descriptor,
                        node_count = meta_info@node_count,
