Interpretation of outputs #11

Closed Kaonashi22 closed 9 months ago

Here is an example of output for one subject. If I understood well, values are averaged across vertebral levels, with the column "D" indicating the index of the averaged slices. In column E ("VertLevel"), levels are numbered from 12 to 2 in descending order. What's the anatomical correspondence ?

When running the script on multiple subjects, should I get one file per subject or all subjects in one file?

I know this can be confusing. In the example below:

VertLevel: Vertebral level, using the labeling convention of SCT. For example, "8" means T1.
Slice (I->S): The axial slices associated with the vertebral level
Size [vox]: The number of voxels within which to aggregate/average the metric
MAP(): The extracted metric (what you want), averaged across Size [vox] using the maximum a posteriori method
