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? On 7/15/2021 2:34 PM, Alejandro Meruelo wrote: > External Email - Use Caution > > I see, thank

External Email - Use Caution I see, thank you. Would statistics on cortical thickness calculations be impacted? Many thanks again, Alejandro On Thu, Jul 15, 2021 at 8:38 AM Douglas N. Greve wrote: > > if you are doing statistics on the surface measures, then they will > impact

External Email - Use Caution 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 On Mon, Jul 12, 2021 at

Not sure I know what you mean. For creating the design matrix, it uses the info from the qdec table. BTW, qdec is deprecated. On 7/12/2021 5:27 PM, Alejandro Meruelo wrote: > External Email - Use Caution > > Hello, > > I had a brief question regarding Qdec vertex-wise clustering. Does >

[Freesurfer] Qdec vertex-wise clustering question

2021-07-12 Thread Alejandro Meruelo
External Email - Use Caution 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
