About¶
graynet
helps you easily extract single-subject network-level features from T1-weighted mri features, as well as ROI-wise statistics, such as:
Cortical thickness, Gyrification, Curvature, Sulcal depth etc
Gray/white matter density, or any other voxel-wise feature
Subcortical morphometric features
Applicable for whenever network-level features are useful, among which common use cases are:
Biomarker development
Brain-behaviour relationships e.g. for the diagnosis and prognosis of many brain disorders such as Alzheimer’s, Parkinson’s, Schizophrenia and the like
Aging (changes in network properties over age and their relations to other variables)
and any other applications wherein single-subject networks and ROI-stats are helpful.
Quick illustration¶
Applicability¶
This package can aid in understanding brain function (relationship of GM network-level features with behaviour) and in imaging biomarker development for the detection of many brain disorders such as Alzheimer’s, Parkinson’s, Schizophrenia and the like.
