Thank you for your reply.

I have download a set of data from Auckland University. The torso surface have 1512 point, but they select 171 electrode when measured the data. Now I have 1512 point positions and its face, and the potentials which corresponding the electrode, now I would like to show the data on the body

surface, and the version of my scirun is 4.7.

In order to describe my problem more clearly, I use a picture to illustrate, the result is wrong, what should I do

Forwarding this question onto our mailing list...

Can you provide more information about the dataset you're using?

I have found a data about ecg, but the data and geometry does not match,
because they select some electorde on body surface . But now, I only
have the electrode coordinate what should I do?
