Hello,

Try:

In > li=Thread[aaa];

(this instruction split your datalist into three lists: one list for each coordinate: the first list is for x-coordinate, the second for y-coordinate and the third for z-coordinate)

and after, you've just to apply Interpolation to each one:

In > Interpolation/@li

Out > {InterpolatingFunction[{{1., 10.}}, <>], InterpolatingFunction[{{1., 10.}}, <>],
InterpolatingFunction[{{1., 10.}}, <>]}


and you obtain three InterpolatingFunction
Now if you plot it (with ParametricPlot3D) you obtain the trajectory of your system.

Regards 
Rudy
