ciftiTools now has a couple functions which make working with parcellations easier. (A parcellation is a single-column dlabel CIFTI or "xifti" object. Each label level, or "Key", represents a "parcel." Each location belongs to exactly one parcel. Parcels are usually contiguous regions--but not necessarily. ciftiTools includes a few of the most commonly-used parcellations. These can be loaded with load_parc. Any other parcellation CIFTI file can be read in with read_cifti.)
apply_parc: Apply a parcellation "xifti" to a data "xifti". Can be used to compute the mean of each column, e.g. for FC calculation, but also supports applying any other function parcel-wise.
parc_vals_to_xifti: Create a "xifti" from a parcellation and a numeric matrix of values corresponding to each parcel.
Other new functions:
remap_cifti: an extension of resampling. Beware, we might revamp this function in the future.
surf_area: computes the surface area attributable to each vertex or face of a "surf" object.
Changes to existing functions:
convert_xifti, convert_to_dlabel: arguments related to levels & labels have been renamed to match factor more closely.
separate_cifti and write_xifti2: now require users to provide either the write_dir argument, or file names for each desired output file. This gives users more flexibility to control which files are written.
view_xifti qualitative color legend: add black outline.
view_xifti, view_volume: print out indices of the selected subcortical slices.
unmask_subcortex: now expects xifti input. If necessary, use the internal function ciftiTools:::unvec_vol to unmask a numeric matrix directly.
Bug fixes:
view_xifti: fix bug where legend image was still written if legend_fname=NULL.
13.1 also includes misc. documentation and warning improvements.
