Hi Nawar,

you are correct that it is a matter of mapping the solution onto your sensor points.  Both of the modules that you mentioned will do mapping, but you will need to find the correct one.  It is one that is after the solution is calculated, however I cannot be more specific unless I know which example you are using.  I am a little confused about which example you are trying to use, so if you could be more specific about the network that you are using,  where is it in the exmple_nets folder or where it is from, I could give you more specific help.

Dear Ms. Elizabeth Jurrus,


I am working with the make_lead_field.srn toolkit, it works fine to generate a matrix connecting the source points with each thorax.tri nodes. But this is not exactly what I need, I would like to connect the source nodes only with sensors points that I already have. As far as I understand the tookit, I suspect the change should be done with the MapFieldDataOntoNodes module or one of the BuildMappingMatrix modules but I am quite not certain where and how. How can I introduce the sensors to this toolkit?


Best regards and thank you in advance,
