Given the platform you are on and the fact that you are using an up-to-date build of GRASS 6.4, I recommend you do this with the new wxPython GUI instead of the TclTk one. I think it will work better for you.

Content-Type: text/plain; charset=us-asciiI am trying to georectify an xy image. I think that I am doing things correctly yet I keep getting an error. Perhaps someone can clear things up for me.
I imported the image into an XY location. I then went to the location that I want to import into and brought up a map so I could click on points.
If then select file-> georectify. I fill in the info and then click Start georectifying. It brings up the manage ground control points window and a display showing the xy map to be georectified. If I click there I can add the GCP xy coords. But if I then click in my original window to select the georgraphic coords I get an error: can't read "b1 coords" : no such variable.can't read "b1coords": no such variable
while executing
"$geoentry insert 0 $b1coords"
invoked from within
"if { [info exists geoentry] } {
$geoentry insert 0 $b1coords
}"
(command bound to event)I can't figure out why it will not let me select the points. I have selected the arrow tool in the map display.
I am using a Mac with William Kyngesburye's binary builds. I have 6.4 RC5-3 Snow with OS 10.6.2
Thanks,
