Hey Group,
I have a couple questions about vbm and Dartel. First
I've run a vbm analysis to explore gray matter volume differences
between two populations in my study. I was able to run vbm for each
subject and extracted gray matter volume values for each subject.
However, when I look at the gray matter images generated by vbm there
appear to be some problems for some of subjects. I'm attaching a .jpg
image of 15 of my subjects anatomical high resolution normalized brains
and a .jpg image of the subsequent vbm analysis (the m0wc1 images).
You'll note how many of the subjects have very strange gray matter masks.
Additionally, I also performed some ROI analyses (Markus, thanks for
sending the code from John), but was unsure what vbm images to feed into
the script. I chose the m0wc1 images. Are these the correct images to
choose?
Lastly, I also wanted to try using DARTEL, but it seems that it is not
compiled for PCWIN 64. Is there a newer version that is? Can I alter
any code to get DARTEL to work?
Thanks for your help!
Best,
-Marc
