Hello,
        Thank you for your replies.  I'm still having a little trouble
working it out.

Details:
What I have are brain images, 30,000 pts on each hemisphere.  The points are
imported to dx from a file in which the points are rendered in loops from
front to back like you were tracing the outline of a brain that was sliced
from front to back.

Questions:
1) despite reading the manual on pick, I can't seem to figure out how to
connect the pick tool.  I was able to have the output of image (image
renderable) connect to the input of pick, but when I try to output the
result of the pick to caption, I get the error "output parameter type and
input parameter type do not match".   Does anyone know how I can get the
output displayed (that is, the 3 coordinates and the 4th data variable), and
also how I can save them to a text file?

2)  when I look in the locations bar in pick, I see that when I click on a
point, it's adds to it 2 numbers.  Any idea what these are?  The data isn't
2-d, it's 4-d (x,y,z,data).

3)  I'm try to select the actual points that make EXACTLY with the input
coordinates from the actual data file.  I can't seem to figure out which
option in pick to make sure I get these values.

4)  some one mentioned used map,  would this be better?

Thank sooo much for your help,
Dave
p.s. I'm obviously new to data explorer, so please excuse my confusion.
Thanks!

In addition to Chris' advice, you can display the coords (as found with 
{Pick}) using {Caption}.
