Mon, 12/31/2012 - 22:34liufeng最近又研究了一下alphasim校正,但是不清楚自己想的对不对,所以来这里和大家探讨下。 其实个人感觉alphasim并不是那么弱,只是很多研究者可能在错误的使用它。最近通过看一些文章发现:alphasim中的平滑核大小并不是我们进行预处理时smooth平滑核的大小。这个大小是需要第三方重新进行估计的。如: 3dFWHM。所以rest中给出的平滑核大小和需要的cluster size就失去了本身的意义。 比如:预处理平滑的时候用的8 8 8,最后会出来如下这个,那么我们alphasim校正时的应该是14.3...7335 reads

Fri, 12/28/2012 - 04:45liufeng各位老师: 做完degree centrality会自动出来一个归一化的图(减去均值除以标准差),请问不归一化的话会有什么不好的吗? 如果在subject内部做归一化,个人感觉会破坏掉原来值的太小,从而导致组比较的时候结果不同(归一化与不归一化)。 有点困惑,望解答下9772 reads
