calculator results compare to the mean and absolute deviation? How do these results compare to your own individual data? Which method is more accurate? The mean was 10 g/mL‚ while the calculator’s results for the line of best fit showed that the density was 9.615736862 g/mL. This is not a large difference‚ but the calculated average is more accurate in comparison to the accepted value of the density of lead‚ or 11.343716 g/mL. The average absolute deviation‚ when done by hand‚ was .8 g/mL.

Root mean square deviation (RMSD): The root mean square deviation (RMSD) is a measure of structural differences that are observed on superimposition of two protein structures at a different time points i.e. current position and previous position. The RMSD values for backbone atoms of each residue were calculated for entire trajectory to see the evolution of structure with time. The RMSD plot is shown in Supplementary Figure S7 where timestep is plotted on X-axis while RMSD (Å) is plotted on Y-axis
