关于回归协变量

Submitted by Lei.Gao on

各位老师: 新年好!元宵节快乐! 我有一个疑问,在DPARSF做功能连接时,有一步要回归协变量,我在想后面的提取ROI时间序列和功能连接,是不是都在回归了协变量之后做的处理?那在统计分析的时候,双样本t检验还要输这些协变量文件吗? 谢谢老师!

请教一下,做组块时,查看脑区激活,在xjview中如何分析? 例如一下的一个cluster该如何分析? Cluster 1 Number of voxels: 149 Peak MNI coordinate: 45 -63 -36 Peak MNI coordinate region: // Right Cerebellum // Cerebellum Posterior Lobe // Tuber // undefined // undefined // Cerebelum_Crus1_R (aal) Peak intensity: 3.7961 # voxels structure 149 --TOTAL # VOXELS-- 149 Right Cerebellum 149 Cerebellum Posterior Lobe

老师: 您好,我将手上的一批BOLD数据在进行预处理时,均没有出现任何报错,但是,当我用DPARSF进行ALFF、fALFF、以及功能连接操作时,matlab则出现了以下报错: Computing ALFF with: "K:\yz10test\FunImgNormalizedSmoothedDetrendedFiltered\003" Read 3D EPI functional images: "K:\yz10test\FunImgNormalizedSmoothedDetrendedFiltered\003".???

voxel-based FC using multiple user defined time courses

Dear REST authors, I'm performing voxel-based FC on my data and for the seed definition I need to specify the time courses. When I use a single time course saved in .txt file I have no problems, but when I save multiple time courses (one for each column) in the same .txt file, REST don't recognize them as separate time courses and produces only one FCmap.

各位先进: mac OSX 10.5.8 matlab 2010a SPM8 (updated to 4290) Rest 1.7 当我在做slice timing时,用DPARSFa 2.0可以顺利地完成,但用DPARSFa 2.1时出现底下的错误 Your TR is 2.0 Failed 'Slice Timing' Improper assignment with rectangular empty matrix. In file "/Users/mac/Documents/MATLAB/spm8/spm_slice_timing.m" (v3756), function "spm_slice_timing" at line 232.
