title: Table S2. List of sequences used in the dated phylogenetic reconstruction for Chamaeleonidae and outgroup taxa

description: Environmental variation can drive patterns of directional selection, often leading to adaptive changes in shape and form. When selection pressures are strong, different lineages may converge on similar phenotypes, or phenotypes may be conserved for a particular habitat type. In the dwarf chameleons (<i>Bradypodion</i>) of southern Africa, it has been hypothesized that some lineages have converged on similar phenotypes (ecomorphs) when they occur in habitats with similar vegetation structure. However, the convergence of lineages into ecomorphs has not been explicitly tested across the genus and could be due to other factors such as morphological conservatism or shifts of entire clades to new trait states. To assess these alternatives, we measured functional morphological traits across 24 lineages of <i>Bradypodion</i> and tested for evidence of phenotypic convergence using time-calibrated phylogenies. Our results indicated that many lineages that do not share a common ancestor, but are from similar habitats, have converged upon similar phenotypes (i.e., tail length, hand size, foot size, casque height), with ecology showing a stronger influence than evolutionary history. We interpret this as adaptive changes in morphology in response to the constraints imposed by different habitat types.<br>

title: Enumerative Discovery of Noncanonical Polypeptide Secondary Structures

description: From the paper: "Enumerative Discovery of Non-Canonical Polypeptide Secondary Structures"

The following is provided: 1) Lowest energy PDB files and 2) CSV files/figures of the delta energy vs RMSD for all 20,475 calculated sequences. A set of the most promising 918 designs are provided as inspiration for future investigations. A significant false positive rate, similar to this study, should be expected from these designs. The two populations are provided as seperate directories.

Energies are in units of kcal/mol/residue. All polymer models are 8 residues. The AIMNet(SMD)-D4 scorefunction was used to evaluate the energies.
