Important note: Some particles may not exist at all times, but the tracking program has identified them as likely the same particle and thus with a continuous identity. However, it is known that occasionally the tracking program makes mistakes with this. |

Data file: pnas09.zip (6.3 MB)
Format of data: This is a textfile with seven columns. The columns are (x,y,z,N_o,c,t,ID). The (x,y,z,diameter) data are in microns. The fourth column corresponds to the N_o variable in our article, which is the number of ordered neighbors the particle has. We use the criterion that N_o > 7 means a particle is crystalline. The fifth column, "c", is the coordination number of each particle: the number of nearest neighbors, defined as particles with centers less than 1.41d away, using the mean particle diameter d=2.30 microns. Each particle has a unique ID number assigned to it. Time t is an integer; to convert to seconds, multiply by 25 s.
