Table S1.xlsx is Table S1, which contains 2D measurements of cell clusters used in Fig. 5 (this is also available from the publisher's website). The folders SMNH X 4447, SMNH X 5331 and SMNH X 5357 contain data from X-ray tomographic analyses of fossils figured in the paper: For SMNH X 5331 (the conical fossil that is the focus of the paper) there are two zip archives: 1. Slice data and Avizo files, containing: - Slice data: the raw scan data (.tif image stack) - Label files for cell clusters and individual cells: Avizo projects (.hx) containing the labels and the files required to open the project file. The cluster labels are based on a downsampled version of the data which is included here as slice data (.tif image stack). Voxel sizes for this file are 0.325 x 1.3 x 0.325 micrometers. 2. Working files, containing: - Surface models: .ply files for clusters and individual cells. - Segmented stacks: the label files as .tif stacks (voxel sizes as per slice data: 0.325 x 0.325 x 0.325 micrometres (cell labels); 0.325 x 1.3 x 0.325 micrometers (cluster labels)). SMNH X 4447 and SMNH X 5357 (two specimens figured for comparison) there is: - Slice data: zip archives of the raw scan data (.tif image stack). The individual slices (.tif images) can be viewed with standard graphics software, and the datasets can be studied in 3D using tomographic reconstruction software such as Avizo (www.vsg3d.com/), Spiers (www.spiers-software.org/), VG Studio Max (www.volumegraphics.com) etc. The Avizo project and label files (.hx and .am files) require Avizo software (www.vsg3d.com/) to be opened. The 3D models (.ply files) are widely compatible with 3D freeware packages such as MeshLab (http://meshlab.sourceforge.net/) or Blender (https://www.blender.org/), or with proprietary software, e.g. Avizo (www.vsg3d.com/), Geomagic (http://www.geomagic.com/en/), Mimics (http://biomedical.materialise.com/mimics). The files relate to the following publication: Cunningham, J. A., Vargas, K., Marone, F., Bengtson, S. & Donoghue, P. C. J. 2016. A multicellular organism with embedded cell clusters from the Ediacaran Weng'an biota (Doushantuo Formation, South China). Evolution & Development
