DISCLAIMER: This algorithm was created by Y. Lanoiselee and D. S. Grebenkov and posted onto the INADILIC website according to the authors' permission. This code can be used for the statistical analysis of single-particle trajectories, under the condition of providing the appropriate credits to the authors and citing the above paper which presents and describes the algorithm. The code aims at identifying "slow" and "fast" phases of a single intermittent trajectory by constructing local convex hulls (LCHs) and using their geometric properties as discriminators between two phases. As the method relies exclusively on geometric characteristics, it is intrinsically model free, whereas its integral-like character makes it robust against noise. The LCH method has been successfully validated on six common models of intermittent motion (see the paper). For further questions, contact directly Y. Lanoiselee (yann.lanoiselee@polytechnique.edu) and D. S. Grebenkov (denis.grebenkov@polytechnique.edu) The authors would appreciate your feedback concerning eventual difficulties, drawbacks and improvements of the method. Please also inform the authors about publications, in which the method was used.
