计算网络各项参数

          各位老师,大家好!本人初入大脑结构功能网络研究这个方向。之前有一批结构数据已经用explorer dti做完了预处理,现在接下来要计算结构网络的各项物理参数比如rich club系数,小世界特性等等。不知道哪位老师处理过结构数据,可否分享一下批处理操作过程。本人不胜感激!在功能网络论坛请教结构网络内容,冒昧打扰,还望老师们谅解!

Degree Centrality and negative correlations

Hi,

I would like to know whether the Degree Centrality calculation is based on positive correlations only, or also on negative correlations? If I set a correlation threshold of r=0.2 will it take the absolute values of correlation and include negative correlations as well? If no, is there a way to calculate DC taking into account both positive and negative correlations at the same time? 

Kind regards, 

Anja Ries
