The atlas data is represented by a set of image files (e.g. 3/4D NIFTI files) along with an atlas description file in XML. The image files contain voxel classification values while the XML file caries the associated label and summary image information.
Atlases come in two flavours:
Tag name | Description | Attributes |
---|---|---|
Tags in header section | ||
name | A text sting to be displayed in any tools when refering to this atlas. | |
type | Probabilistic, Label. | |
imagefile | Relative path to the location of the atlas image | |
summaryimagefile | Relative path to the location of the atlas summary image | |
Tags in data section | ||
label | Text corresponding to this volume's label |
