thanks for a great software – our lab has thoroughly enjoyed using BrainSuite thus far!
We are currently working on a project in PTSD, so we are interested in identifying changes to the amygdala and hippocampus. Unfortunately, when running the SVreg, we only receive GM and WM output for either region, and only not a number (“NaN”) for cortical thickness. Could anybody clarify why that is?
Thank you for using BrainSuite and very happy to hear that you like it.
The SVReg module computes thickness only for the cortical surface using inner and pial cortical surface representations.
Since the hippocampus and amygdala are subcortical structures, their volumes are not computed, but gray and white matter volumes are reported. The ‘thickness’ computation for hippocampus will involve generating surfaces only for that structure and not the entire brain. We don’t have that functionality implemented.
