title: Data from: Integrative approach uncovers new patterns of eco-morphological convergence in slow arboreal xenarthrans

description: <b>A) Alfieri et al. 2021_statistical analysis.R</b>: code allowing to replicate all the steps of the statistical analysis. All the functions are applied, as example, on humeral data (starting from SOM1_humeri.xls). The same steps can be applied to femoral data. The file also include the univariate version of convevol functions. <b>B) Choloepus didactylus ZMB Mam-102636_humerus_TEMP.ply and Bradypus sp ZMB Mam-33806_femur_TEMP.ply</b>: humeral and femoral templates which were subjected to inflation and decimation. Details and operations in which these models are involved are explained in the text <b>C) humeri3DGM_rep_array</b> and <b>femora3DGM_rep_array</b> : R workspaces to be loaded to analyse the arrays 'sorted', including landmark coordinates needed for the repeatability test on humeral and femoral external shape data <b>D) MacroSphereRect.ijm</b>: Fiji macro allowing to extract a spherical Region of Interest (ROI) of trabecular bone from an articular joint, as detailed in the text and in the macro <b>E) SlicebySliceCSP.ijm</b>: modified version of the macro from Amson, 2019 (details in the text), allowing to automatically compute non-directional cross-sectional properties with a slice-by-slice approach on thresholded, purified and oriented CTstacks. <b>F) SOM1_humeri.xls</b> and <b>SOM2_femora.xls</b>: complete datasets and information for the all the analysed humeri and femora. For each of them they include 1. Catalogue number, collection and taxon 2. CTscanning resolution 3. Metric measurements taken on the proximal[ <i>(HeadPDLen(mm), HeadMLLen(mm), HeadAPLen(mm)</i>] and distal [<i>CapPDLen(mm), CapMLLen(mm), CapAPLen(mm)</i> for the humeri;<i>LatConPDLen(mm), LatConMLLen(mm), LatConAPLen(mm) MedConPDLen(mm), MedConMLLen(mm), MedConAPLen(mm)</i> for the femora] epiphyses. 4. If the specimen was discarded from 3D GM analysis, <i>DiscGM=1</i> 5. If the specimen requested the process of correction for biased slices during the computation of CSP, <i>SliRemCSG=1</i> 6. If the specimen was too filled with sediment or too damaged and the 50% level was not preserved, <i>DiscCSG=1</i> 7. If extreme diaphyseal slices were biased, needing manual restoration to allow the data interpolation (as explained in the text),<i>ExtSliRest=1</i> 8. the specimen was too filled with sediment or too damaged but the 50% level was preserved and analysed, <i>Only50=1</i> 9. If the 50% level (preserved as in point 8) needed manual restoration to be analysed, <i>Rest50=1</i> 10. <i>DiscProxTrab</i> and <i>DiscDistTrab</i> for the humerus, are =1 if the extracted ROIs of trabecular bone were discarded for the proximal and/or distal epiphyses, respectively. <i>DiscProxTrab</i>, <i>DiscLatConTrab</i> and <i>DiscMedConTrab</i>, for the femur, are =1 if the extracted ROIs of trabecular bone were discarded for the proximal epiphysis, lateral condyle and/or medial condyle, respectively. 11. <i>RestProxTrab</i> and <i>RestDistTrab</i> for the humerus, are =1 if the extracted ROIs of trabecular bone from the proximal and/or distal epiphyses, respectively, needed restoration in order to be analysed. <i>RestProxTrab</i>, <i>RestLatConTrab</i> and <i>RestMedConTrab</i>, for the femur, are =1 if the extracted ROIs of trabecular bone from the proximal epiphysis, lateral condyle and/or medial condyle, respectively, needed restoration in order to be analysed. 12. Diameters of the extracted trabecular bone ROIs (<i>ROIproxDiam (mm) </i>and <i>ROIdistDiam (mm)</i> for the humerus; <i>ROIproxDiam (mm), ROILatConDiam (mm), ROIMedConDiam (mm)</i>; for the femur) 13. Relative resolution for each trabecular bone (computed and interpreted as detailed in the text); <i>ROIproxRelRes</i> and <i>ROIdistRelRes</i> for the humerus; <i>ROIproxRelRes</i>, <i>ROILatConRelRes</i> and <i>ROIMedConRelRes</i> for the femur; 14. Body mass proxy (BMproxy), computed as detailed in the text and in Supplementary Information 1 15. <i>PC1-PC38</i> (for the humerus) and <i>PC1-PC39</i> (for the femur): PC scores extracted from the 3D analysis 16. <i>ResC50 (%)- CSSAver</i>: CSP raw data, extracted from both the 50% level (Parameter50) and averaging CSP along the diaphysis (ParameterAver), as detailed in the text 17. <i>DAprox- Av.Br.LenDist(mm)</i> for the humerus; <i>DAprox-Av.Br.MedCon(mm)</i> for the femur: trabecular parameters raw data from each of the analysed articular joint (as detailed in the text). <b>G) SOM3-SOM13.xls</b>: raw data from three repeated data extractions on a subset of 7 humeri and femora, to assess repeatability (detailed in the text) <b>H) SuppInfo1_AdditionalMethods.pdf</b> <b>I) SuppInfo2_AdditionalResults.pdf</b> <b>J) xenarthra_tree.nex</b>: time-calibrated phylogenetic tree used in this study<br><br>
