I think you want to use flat.[xyz], but I'm not that familiar with the
patch function

Hi Bruce,
Thanks thats great to know, I have an ellipsoid fitting function ready for the
job.
I've started the process of getting the occipital flatpatch into MATLAB
following some forums posts, the best route seems to be as follows but i'm
getting an error message.
I can't find anyone posting
Hi Sarah
I don't think we have anything for ellipsoid fitting, although Oliver
Hinds did some in his paper on V1. Should be straightforward enough in
matlab. The data are in 2D mm coords

Hi Bruce
Thanks for the information on the flat patch, thats great that the
relationships are preserved!
With that in mind do you know if freesurfer has any inbuilt functions to take
the kind of measurements that I was describing? Or will my MATLAB based
proposal be the best option do you thin
Hi Michael
I usually check visually to see if things worked. Failures occur if you
dno't cut all the way through. For example, if you are cutting down the
fundus of the calcarine but miss a spot so that there is a connection from
upper to lower bank. You could cut down the lateral surface inst
Hi Bruce,
Is there some way to know when cuts have been made correctly so that
distortion can be minimized? (Or conversely, some way to know when a given
patch has or will undergo "too much" distortion during flattening?
Thanks!

Hi Sarah
the unfolding tries very hard to preserve exactly this - the metric
properties. If you cut off the occipital third of cortex and flatten it
(after introducing some cut along the axis of the "cone") you should be
able to get to around 10% distortion or below, which I assume is good

Dear all,
I am looking to take two measures within the visual cortex.
1) A measure of width and length for each activation cluster overlaid onto the
flattened cortical surface.
2) A measure of spacing between each cluster
I can find how to take measures of area but I specifically want to know th
