Hi Dr. Fischl,
Have you had a chance to look at the recons I sent?

Hi Brent
if you upload the subjects and point us at the specific locations you
expect to see effects and the ones you don't we will take a look
cheers

What you really want to simulate is an underlying geometric deformation
(like atrophy) that gets propagated through an image formation model to
create an atrophic image. I don't think multiplying the image intensities
is a good model for what you want. Atrophy doesn't look like a uniform
darken
Yes, I'm multiplying the image intensities by a scaling factor. Sorry if
that wasn't clear.

Hi Brent
a quick look and it seems that your answer is "yes"? You are multiplying
the image intensities by some scale factor?

Yes. Here is the MATLAB script:

maskraw=load_nii([pwd,'/',
num2str(i), '/pre.nii'])a=single(squeeze(raw.img));
c1_raw=load_nii([pwd,'/', num2str(i),

is gray around edges. Threshold to make it binaryc
Hi Brent
are you saying you just multiplied the gray matter intensities by some
scale factor (>1)?
