Hi Frank,

just a quick question: Can one perform differential tractography between two groups or longitudinally, but using covariates? This would be great if it were to be possible.

Best,

Aleksi

Hi Aleksi,

This will be correlational tractography: https://sites.google.com/a/labsolver.org/dsi-studio/Manual/diffusion-mri-connectometry

Connectometry is the statistical approach to get inference from correlational tractography.

Best,

Frank

Hi Frank,

thank you for the answer. Just checking that if I got this right: Can one perform cross-sectional group comparisons in the group connectometry analysis -option by inputting 1 and -1 for the groups and using that as the study variable?

Thank you for your support and answer.

Best,

Aleksi

Yes, we can do that.
