Hello,
I had a brief question regarding Qdec vertex-wise clustering. Does Qdec use the data in the raw imaging files or the qdec.tables.dat file to generate the vertex-wise clustering results for cortical thickness group comparisons?
Many thanks for your assistance, Alejandro
Not sure I know what you mean. For creating the design matrix, it uses the info from the qdec table. BTW, qdec is deprecated.

This is very helpful, thank you! Do the recon-all generated FreeSurfer data (e.g., surfaces) impact any of the statistical calculations or are they primarily used for figure generation for Qdec?
Many thanks again, Alejandro

if you are doing statistics on the surface measures, then they will impact the calculations

I think i'm misunderstanding your question. Typically, you are running the stats on the thickness, so of course anything that changes thickness would impact the stats. Am I missing something?
