关于height extent校正

Submitted by liufeng on
Significant clusters of activation were determined using the joint expected probabil- ity distribution with height (p < .001) and extent (p < .001) thresholds, corrected at the whole-brain level. 我们的extent不是体素个数吗?extent (p < .001)是什么意思呢?height (p < .001) 是每个体素的p值吧

确认一下文章中是不是SPM的FWE或FSL的cluster校正。可以阅读一下这方面相关的参考资料。它们会给出团块水平的p值,extent应该是这个。
