Thu, 06/06/2013 - 17:54fish尊敬的各位老师: 我想问ica提取出来z值应该怎么解释呢?我做的是case-control用双样本t检验后选取其中的roi,再提取z值,这个指的是roi在这个大脑网络的连接强度?还是指? 再补充一下:有文章提出“在双样本t- 检验的结果中提取出患者相比正常对照增高及降低的脑区,作为感兴趣区,再提取感兴趣区内每个患者的平均z 值”,我想问的是提取出来的ROI应该用的是rest里面extract ROI signals吧?...5207 reads

Tue, 06/04/2013 - 20:14bernie29Hi, I just begin with DPARSF, but in DPARSF_V2.2_130309\Templates all the masks 91x109x91 seem to be empty. So I replaced them by those ones of SPM8, but i prefer to signal this problem. Thanks. Antoine6984 reads

Tue, 06/04/2013 - 17:25rumen老师: 您好,我在计算完两组被试的DC之后,进行双样本T检验,把有显著差异的脑区提取出来,然后想对每组被试提取感兴趣区域的mDC值。 请问: 1.ROI的制作是用对应ALL模板中不同脑区的阈值提取脑区作为mask好还是采用以Peak点为中心的球形ROI比较好呢? 2.提取感兴趣区域是不是把每组所有被试的各ROI值提取出来,然后用SPSS统计比较两组的差异吗?可不可以对每组被试的单样本T检验校正后的cluster结果提取ROI值? 谢谢您!5304 reads

Sat, 06/01/2013 - 11:40qianqian臧老师,您好! 我一个fMRI研究收到了两个比较难以回答的审稿意见,想向您请教下: 1. 我同时记录了两组被试(假设为组A和B)、两个阶段(反应阶段 和 反馈阶段)的fMRI结果,分别对两组被试在两个阶段的大脑激活模式进行了分析。 在报告数据时,我使用了三种阈值: 针对反应阶段:组内比较使用的阈值是 FDR<0.01, K>50;组间比较是FDR<0.05, K>50; 针对反馈阶段:组内比较和组间比较的阈值都使用FDR<0.001,K>50....11954 reads
