Cell Migration (MSD and RMSD)


1.You are given the mean squared displacement (MSD) in microns^2 and time in minutes for one cell’s position.  Plot MSD and root mean displacement (RMSD) versus time.  Then plot the derivative,  d[log(RMSD)]/d[log(time)] versus time.  This derivative is the exponent a in the expression  RMSD ~ time^a.  Comment on the ‘random walk’ nature of this cell’s migration. 

The MSD information is given in the attached Excel sheet
