我有A、B两组被试,前期做了ALFF的双样本T检验,现在想用这些T检验显著的脑区做ROI_Wise的功能连接,数据已经通过DPARSF软件将默认的那些协变量去掉了,但是我想去掉年龄和受教育年限这两个协变量,怎么做那? -

Dear all,
I've been conducting a 2 sample t-test with mALFF data using REST. It results with a T-image and I cannot find any spm-like output (table with significance level).
Is there any way to get this info/table?
Thanks very much!

我的静息态实验有两个组,A和B,先给A、B组在REST软件中分别做了一个单样本T检验,此时没有选择MASK,然后用Slice Viewer分别打开这两个组的单样本T检验结果,使用Alphasim(0.05)矫正,Cluster个数选择的是324,我现在为了得到双样本T检验的MASK,是将正负激活的Clusters都保存下来还是只保存Only+啊,这两种有没有区别啊,我计算MASK时的表达式是“(i1>0+i2>0)>0”. -

请教一下:
经过VBM得到了一组人平均的WM图,然后我想制作一个该组人的WM MASK,应该怎么做?是不是有一种做法:set the thresholded to ensure 80% tissue type probability,这个应该怎么做啊?
谢谢!!!
或者是不是可以直接设阈值,阈值是经验值,那么一般应该设多少,0.2?有没有相关参考文献?
再次感谢!!! -

老师:
你好!
用rest做双样本T检验时,怎么操作协变量这一栏,比如要剔除年龄、性别,课件视频上说加入text文件,是直接把数据写到上面吗,以什么样的格式呢,我试了我几次都不行,请教老师这一步操作怎么做?
谢谢! -

hi,
I'm new to this topic and would be interested if there is any effort to port REST to octave -
