What is the meaning of DPARSFAs outputs

Submitted by tara.fd on

Hi,

When I run dpabi to measure Reho, DegreeCentrality, ALFF, and fALFF, there are three outputs for each subject, for example: DegreeCentrality, mDegreeCentrality, and zDegreeCentrality.

My question is that what does m- and z- mean?

Thanks,

Tara

Hi Tara,

m- means the average metric value (e.g., reho, alff) across all brain has been substracted from each voxel's value.

z- means z-standardization (minus average metric value then divide standard deviation).

Best,
