MBAT 3.0 File Formats

Atlas File Format

The .atlas file format is an XML based file format to specify a labelled atlas object which consists of:

1. 3D volume data (ie: MR data)
2. label set(s):
   1. 3D label volume (ie: same dimensions as 3D volume data where each voxel specifies an integer ID associated with a label)
   2. Label file (ie: ontology file that maps colors to label IDs and describes the relationships between the labels)

The MBAT3.0 .atlas file format differs from the MBAT2.0 format since it allows multiple label sets per 3D volume. An example .atlas file is given below for an atlas with 2 label sets:

<?xml version='1.0' encoding='utf-8'?> <Atlas creator="seth" date="Nov 9, 2006"> <volume src="TS25.mri.hdr"/> <labelhierarchy> <label src="TS25.labels.hdr" alpha="0.5"/> <hierarchy src="TS25.labels.ilf"/> </labelhierarchy> <labelhierarchy> <label src="TS25_gross.Labels.hdr" alpha="0.5"/> <hierarchy src="TS25_gross.Labels.ilf"/> </labelhierarchy> </Atlas>
