Every folder contains:
-    a tif-file with captured image series
-    a PIV*-folder with four PIV-files for every frame pair. The four files belong to intermediate results of the multistep PIV. The final PIV-result is given in the file step2*.dat.nmt.
        The PIV result will be stored in a plain text file. Each line in this file correspond to each PIV vector and comprised of 16 columns:
        x     y     ux1     uy1     mag1     ang1     p1    ux2     uy2     mag2     ang2     p2     ux0     uy0     mag0     flag
        -- (x,y) is the position of the vector (center of the interrogation window).
        -- ux1, uy1 are the x and y component of the vector (displacement) obtained from the 1st correlation peak.
        -- mag1 is the magnitude (norm) of the vector.
        -- ang1, is the angle between the current vector and the vector interpolated from previous PIV iteration.
        -- p1 is the correlation value of the 1st peak.
        -- ux2,uy2,mag2,ang2,p2 are the values for the vector obtained from the 2nd correlation peak.
        -- ux0, uy0, mag0 are the vector value at (x,y) interpolated from previous PIV iteration.
        -- flag is a column used for mark whether this vector value is interpolated (marked as 999) or switched between 1st and 2nd peak (marked as 21), or invalid (-1). 
        According to the PIV-Fiji-plugin as provided by Qingzong Tseng, used also in : 
        Tseng, Q. et al. Spatial organization of the extracellular matrix regulates cell-cell junction positioning. Proc. Natl. Acad. Sci. 109, 1506–1511 (2012)
-    two traj*.dat files, belonging to particle positions of the corresponding simulation with monod/teissier uptake. 
        Columns correspond to 
        1 : time | 2 : cellID | 3 : rx | 4 : ry | 5 : rz | 6: species | 7 : vx | 8 : vy | 9 : vz | 10 : fx | 11 : fy | 12 : fz | 13 : B(g) |
        -- rx,ry,rz 3D coordinates of particle
        -- species is either 0 (living cell) or 1 (wall-particle)
        -- vx,vy,vz 3D velocity of particle
        -- fx,fy,fz 3D force of particle
        -- B(g) growth force constant dependent on local g-concentration
        Note that due to the simulation being 2D, rx=constant and vx=0=fx.
-    two g*.dat files, belonging to nutrient concentrations of the corresponding simulation with monod/teissier uptake. 
        Columns correspond to 
        1 : time | 2 : gridx | 3 : gridy | 4 : gridz | 5 : g-conc | 6: kcons | 7 : kprod | 8: Dlocal |
        -- gridx,gridy,gridz coordinates of lattice side
        -- kcons local nutrient consumption rate
        -- kprod local nutrient production rate (always zero)
        -- Dlocal local diffusion constant
