[Camino-users] Synthesis Using Analytic Models

[Eleftheria Panagiotaki]

Hi Julio,

Here is an example for an analytic model with crossing fibres (arbitrary
angle):
Ball StickStick:


datasynth -synthmodel  compartment 3 BALL 0.4 1.7E-9  Stick 0.3 1E-9
*1.2 -4.5* Stick 1E-9 *0.0 0.0 *-schemefile cross.scheme -voxels 1
-outputfile BSScross.Bfloat


In bold are the theta and phi angles  of the colatitude and the
longitude of your axon orientation respectively which you can specify.


I hope this is clearer now,


Laura
