 Analiza statystyczna dynamiki subdyfuzyjnej na podstawie video z eksperymentu Goldinga-Coxa
 A statistical analysis of subdiffusive dynamics in the Golding and Cox microscopy video

Abstract.  I.Golding and E.C.Cox [Phys.Rev.Lett. 96, 098102 (2006)] tracked the motion of indi-
vidual fluorescently labeled mRNA molecules inside the live E.coli cells. They found that in the set
of 23 trajectories from 3 different experiments, the automatically recognized motion is subdiffusive
and published an intryging microscopy video. Here, we extract the corresponding time series from
this video by images segmentation method and present its detailed statistical analysis. We found
that this trajectory was not included in the data set already studied and has different statistical
properties. It can be better fitted by 
- stable or normal-inverse-Gaussian distributions. In contrast
to earlier studies, this shows that fractional Brownian motion is not a best model for the dynamics
documented in this video.
