<![CDATA[Obtain material properties from material database]]>Hi,

When using the GUI, drag and dropping a ViP model to the material settings automatically creates the tissue properties and assigns entities of the ViP model to each tissue property.

I am trying to perform the same task through the python API.
Assuming that I obtained all ViP model entity names, how can we assign automatically the tissue property from the database ?

thanks

yes, i managed to get the corresponding material with :
tissue_X_entity.MaterialName
Each entity of the anatomical model has this attribute which is visible also through the GUI.
thanks

Have you tried doing exactly that through the GUI and then right clicking the simulation and selecting 'To Python..' if I remember correctly that shows you how to assign materials to the database.

Just tried it and I get something like this:

import s4l_v1.materials.database as database

# Adding a new MaterialSettings
material_settings = acoustic.MaterialSettings()
components = [entity__block1]
mat = database["IT'IS 4.0"]["Brain (Grey Matter)"]
if mat is not None:
	simulation.LinkMaterialWithDatabase(material_settings, mat)
else:
	# Fallback if material is not found
	material_settings.Name = "Brain (Grey Matter)"
	material_settings.MassDensity = 1044.5, Unit("kg/m^3")
	material_settings.AttenuationCoefficient = 1.2, Unit("Np/m")
simulation.Add(material_settings, components)

Never tried it with the ViP model but should work.
