strings <output file> < timestep index> <threshold> <sigma matrix file> <trajectory_list_name>
<target>
Calculates mean string length, mean number of strings, string order parameter, and distribution of string lengths. The target should be a trajectory list of mobile particles. This can be produced via the “find_fast” command. Threshold sets the threshold (as a multiple of sigmaij for each particle pair) within which one particle is considered to have replaced another. A standard value for this is 0.6. Also creates a trajectory list called <trajectory_list_name> containing all particles in strings for further analysis.
Sigma matrix file specifies the sigmaij for all interaction types as described in the n_fold command.
