separate_cifti wrapperCalls separate_cifti using the file names listed in the
argument sep_fnames.
separate_cifti_wrapper(
cifti_fname,
brainstructures = NULL,
ROI_brainstructures = NULL,
sep_fnames = NULL,
write_dir = NULL,
wb_path = NULL
)File path of CIFTI-format data (ending in ".d*.nii").
Character vector indicating which brain structure(s)
to obtain: "left" (left cortical surface), "right" (right
cortical surface) and/or "subcortical" (subcortical and cerebellar
gray matter). Can also be "all" (obtain all three brain structures).
Default: c("left","right") (cortical surface only).
If a brain structure is indicated but does not exist, a warning will be raised and that brain structure will be skipped.
Character vector indicating which ROIs should be
obtained. NULL (default) to not get any ROIs. Otherwise, this should
be a subset of the brainstructures argument.
ROIs are typically the medial wall mask for the cortex and subcortical mask for the subcortex.
(Optional) Where to write the separated files (override their default file names). This is a named list where each entry's name is a file type label, and each entry's value is a file name indicating where to write the corresponding separated file. The recognized file type labels are: "cortexL", "cortexR", "ROIcortexL", "ROIcortexR", "subcortVol", and "subcortLabs".
Entry values can be NULL, in which case a default file name will be
used: see cifti_component_suffix. Default file names
will also be used for files that need to be separated/written but without a
corresponding entry in sep_fnames.
Entries in sep_fnames will be ignored if they are not needed
based on [ROI_]brainstructures. For example, if
brainstructures="left", then sep_fnames$cortexR will be
ignored if specified.
The write_dir argument can be used to place each separated file in
the same directory.
Where should the separated
files be placed? NULL (default) will write them to
the current working directory.
write_dir must already exist, or an error will occur.
(Optional) Path to Connectome Workbench folder or executable.
If not provided, should be set with
ciftiTools.setOption("wb_path", "path/to/workbench").
