老师您好！
近期有一篇关于动态功能连接稳定性的论文在投，审稿人提问如下：In the section of Functional stability calculation, the formula of KCC included N to denote the number of connections of each gray matter voxel with all other gray matter voxels. So how did the authors threshold a FC value into a binary connection?
我在阅读Functional Stability提出的论文（Stability of dynamic functional architecture differs between brain networks and states）时，看到的这句话：“Analyses were confined to a grey matter mask, which was created by thresholding the mean grey matter density across participants at 0.2 and intersected with a group mask of 90% coverage of functional images.”是否能解答审稿人提出的问题呢？
非常期待得到您的回复。
“how did the authors
“how did the authors threshold a FC value into a binary connection”
FC map 没有卡阈值。
实际上KCC操作是在不同时间窗做排序操作。
