Wed, 03/18/2009 - 10:00YAN Chao-GanDear Dr. YAN Chao-Gan, My name is Phuong Hoa, I am studying in Korea. I found your REST toolkit and I am interested in it. Now I try to measure the functional connectivity from fMRI data with task-related (visual and motor stimuli). I used ROI-wise with AAL...9846 reads

Wed, 03/11/2009 - 09:11adminDear SONG Xiao-Wei and YAN Chao-Gan: Thank you for making REST fmri analysis software available. It has been very helpful in my analyses. I have a question about how the software analyzes covariables. I notice that you add both a linear and a mean regressor...9008 reads

Tue, 03/03/2009 - 10:36ZangYFIn a few earlier studies, spatilly smoothing was performed before ReHo analysis. However, Mr. LONG Xiang-Yu found that, for some voxels, the ReHo value is very high because spatially smoothing certainly increase the local similarity. That...7699 reads

Wed, 02/25/2009 - 12:26junesums用SPM5的PairedTTest处理数据时,选择刺激组和对照组数据的先后顺序对结果有影响么? 我分别试了对调它们的顺序,然后contrast都是1 -1,发现结果一模一样,T值的正负也是一样。 如果说数据选择的先后顺序没有影响,那应该如何来解释结果呢?比如说刺激数据在前,对照数据在后,contrast是1 -1,那T值是正值的脑区代表的是刺激>对照,还是刺激<对照?12991 reads
