To use POI information

Hello everyone,

I am trying to understand how can I use the POI information for LM data in Castor. It is mentioned that by default it will be used if present in the datafile. How do I include the POI information in the data file?

I will be very glad to get some help to understand it.

Thank you very much.

Best regards,

The use of position of interaction (POI) was thought out since the beginning of the CASToR design, however it is not yet available.
The reason for this is that the computation of the sensitivity matrix in case of continuous POI information is still a subject of research.
CASToR does not provide any solution yet.

Can I ask where did you see this information that the POI will be used if present in the datafile (we probably forgot to remove it from every places) ?

We may provide support to enable and read POI information from the datafile to its consideration in the projector (since everything is almost implemented) in a future version.
However, for the aformentioned reason, we may not provide any solution for the computation of the sensitivity image and let it to the responsability of the user.

Sorry for that !
