[Camino-users] Synthesis Using Analytic Models

[Eleftheria Panagiotaki]

Hi Julio,

With datasynth and the white matter analytic models you can define your
intracellular , extracellular and third or fourth compartment and their
parameters. In the case of the intracellular compartment (cylinder, stick
or gammadistributed radii cylinders) you can define the angle of the
intracellular's compartment's orientation. To my knowledge there is no
constrain that the angles have to be orthogonal in datasyth.

I hope this answers your question,

Laura
