Download a neuromaps annotation — fetch_neuromaps

Download brain map annotation files from the neuromaps OSF repository. Surface annotations return two files (left and right hemispheres), volume annotations return one.

Usage

fetch_neuromaps_annotation(
  source,
  desc,
  space,
  density = NULL,
  resolution = NULL,
  hemisphere = NULL,
  data_dir = neuromaps_cache_dir(),
  overwrite = FALSE,
  verbose = TRUE
)

Arguments

source: Data source identifier (e.g. "abagen", "beliveau").
desc: Map descriptor key (e.g. "genepc1", "feobv").
space: Coordinate space (e.g. "fsaverage", "MNI152", "fsLR").
density: Surface vertex density (e.g. "10k", "164k"). Mutually exclusive with resolution.
resolution: Volume voxel resolution (e.g. "1mm", "2mm"). Mutually exclusive with density.
hemisphere: Hemisphere ("L" or "R").
data_dir: Directory for cached downloads. Defaults to neuromaps_cache_dir().
overwrite: Re-download even if cached file exists.
verbose: Print progress messages.

Value

Character vector of downloaded file path(s).

Examples

if (FALSE) { # interactive()
fetch_neuromaps_annotation("abagen", "genepc1", "fsaverage", density = "10k")
}
