DPARSFA,静息态预处理,标准化后的图片有黑点
严老师您好!我想问一下,使用DPARSFA做预处理,发现标准化完成后的图像都有小黑点,这种情况是什么造成的?以及该怎样解决?

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

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!
fmri预处理之后怎么做置换检验,置换检验之后怎么做多重校正,多重校正是否可用于置换检验,希望能得到大家解答

老师您好,当用dpabi做统计分析时,当添加同样维度的mask时,会报input too many arguments的错误,当不添加mask时,就不会报错,但是permutation test会报错
