Wed, 12/07/2011 - 22:44liufeng版主好： 请教一个问题，在我看种子区域到全脑算功能连接的文章一般是这么做的。将预处理的静息态数据（时间头动校正配准去漂移滤波），提取出种子区域的平均时间序列，然后进行回归头动、全脑信号、白质、脑脊液信号，然后把全脑每一道信号也进行回归处理，最后算时间序列的相关。 我感觉dparsf是这样做的，预处理后（filter后），先把全脑每个体素的时间序列进行回归头动、全脑信号、白质、脑脊液信号，然后提取出种子区域的时间序列，和全脑其他每一个体素算相关。因为我在dparsf做fc的时候让我选择回归后的文件夹，...6254 reads

Tue, 12/06/2011 - 14:27stevenlee697各位老师好，我是一名初学者，进行感音神经耳聋的研究。现在双样本检验后，得到T值，用REST SLICE VIEW进行图像显示，ALPHASIM校正中，当RMM=4时，XJVIEW显示有18个CLUSTER;RMM=5时有11个，RMM=6时有7个。不是说RMM=4时是面对面的方法，校正更严格，怎么CLUSTER还最多？？再有我应该用哪个RMM值？另外，怎么用XJVIEW的报告制做表格，一个CLUSTER中有很多个脑区（从多到少的VOXEL）选哪几个呢？多谢，多谢！！7666 reads

Mon, 12/05/2011 - 14:44liufeng最近看文献，只知道vbm经过modulate后是volume，不经过modulate是的density，不过具体表示了什么还不是很清楚。而且为什么经过modulate就是体积也不是太清楚。下面一段话是文章中的，没太理解，请指点下，谢谢。还有，用哪一个指标比较好也没有具体的说法吧（体积还是密度？），是不是喜欢用哪种就用哪种？有没有什么经验呢？ Gray matter values for unmodulated images are typically referred to as gray matter...7847 reads

Sat, 12/03/2011 - 07:15Chris StevensI have used SPM to preprocesses my data before using the REST utility to convert the data from .nii to niftiPairs. But I am now running into problems and I receive errors and warnings in many of REST's tools about the dimensions of my images. Here are all the...4581 reads
