Excel file containing raw structural and circular dichroism data supporting the paper 'Feature importance in multi-dimensional tissue-engineering datasets: Random forest assisted optimisation of experimental variables for collagen scaffolds'. The excel file contains two sheets. The first sheet contains the structural data (pore size, percolation diameter and median interconnection diameter of each of the nine individual measurements made across each condition). The second sheet contains the raw circular dichroism data including the backgrounds for each solvent.

The codes used in the second sheet are consistent with the codes found in the paper: A-X = undialysed collagen in acetic acid A-D = dialysed collagen in acetic acid A-N = dialysed collagen in acetic acid and NaCl

H-X = undialysed collagen in hydrochloric acid H-D = dialysed collagen in hydrochloric acid H-N = dialysed collagen in hydrochloric acid and NaCl

W-X = undialysed collagen in water W-D = dialysed collagen in water W-N = dialysed collagen in water and NaCl
