B factor based color scheme. Structure of vinculin tail with CA atoms represented in stick model colored by B-factor values. All the B-factor values in the coordinate file are set to zero and the mobility parameter values are replaced for the selected CA positions. Inverse line width values are used in the case of experimental values (multiplied by 1.5 times to facilitate comparison). Color coding bar is shown on the right side with the scale from zero (rigid) to one (mobile). However, experimental values for the positions 901, 909, 927 and 934 were not shown due to non availability.
