Before revision:  Taking the cutoff distanceas variable, the paths are self similar above 6.8 \AA with a fractal dimension of 1.12 , remarkably close to Euclidean dimension. Below 6.8 {\AA} , paths are multifractal  .
After revision:  Taking the cutoff distanceas variable, the paths are self similar above 6.8 \AA with a fractal dimension of 1.12 when calculated with step lengths larger than 6.8 {\AA} , paths are multifractal .
