Dear SPM group,
I have VBM data and neuropsychological data of three groups of patients.
One of the groups performed worse on several cognitive domains. I want to
test whether this decreased performance is associated with decreased total
white matter brain volume.
For the VBM analysis I used the VBM tool Jena script (http://dbm.neuro.uni-
jena.de/vbm.html).
In the output file I found a textfile vbm_volumes.txt.
Are the volumes in this text file modulated? Are they corrected for total
brain volume?
What do I have to do to get total volume GM, total volume WM and total
Brain volume?
Thank you in advance,
