I agree. The average looks fine, and the stuff at the bottom is because we don't automatically redraw the graphics window. You need to click redraw (or alt-r when the focus is in the graphics window) is you obscure part of it.

As far as the first, This happens sometimes when you make your own average
subject.  You just need to inflate it more.  I will try to dig up an old
email I have on the commands.

As for the second, just click the redraW BUTTON

Hello again,
My questions refer to the attached image.
The image is of the average subject I created from our subjects using the
"make_average_subject" command.  As you can see, in an inflated view there
are many gyri and sulci looking structures that shouldn't be there.
Clearly something is not right.

My first question is what aspect of our subjects' brains could be causing
this?  I have inspected the brains in tksurfer and have not found any
defects that could account for this.

My second question refers to the oddness at the bottom left of the image.
That is something I notice happening all the time.  Everytime I drag any
window across the tksurfer or tkmedit window that happens.  It goes away
once I rotate the brain or zoom in or out or anything like that.  Is this
something that people have encountered before or is this an anomaly unique
to our system?

Once again, I really appreciate any help these matters.

Thank you,
Devdutta
