    Dear all, I would like to know if the bug that was found in AFNI's AlphaSim (and was then corrected), was also fixed in REST's AlphaSim. I could see that others have also asked this, but I could not find an answer. Best, Patrik

    老师们好! 我在做两组被试(正常及病例组)两个亚频段(S4,S5) ALFF的分析,使用贵团队开发的dpabi V2.3 mixed effect analysis  运行时报错,我试过把协变量去掉以后运行成功,重新加入协变量后再次报同样的错误。我检查过数据的维度和mask 是一致的,协变量我是按照视频里说的方法在每个TXT文档下放四列(age,sex,eduyear,mean FD),顺序与group image对应,group image加载的顺序参照教程(Group1condition1,...

    老师:       您好,最近我一直在查关于双因素析因分析的资料,对此有些疑惑。如下文献是用SPM5做2X2的(基因X诊断)的双因素析因分析,他们是先分析诊断的主效应,然后再分析诊断与基因的交互效应。但我从统计学的书中看到的是:双因素析因分析首先要分析各因素的交互效应,若有交互效应后再进一步分析各因素各水平的单独效应;若无交互效应则各因素相互独立,才可以分析各因素的主效应。目前我只查到中国人发的这方面文献,而他们都像下面文献这样分析。难道是统计学的书错了吗?...

    老师:      您好,我是最近刚开始接触fMRI,有几个关于Alphasim校正的问题想下请教各位老师,还是希望老师能在百忙之中帮忙解答:       一、用最新版DPABI对三组数据进行ANOVA分析时,同时进行了post-hoc,听严老师在最新的视频教程里说到post-hoc是已经经过校正的,那么在看ANOVA结果时P值如果选择0.05的话,再看post-hoc结果时,P值是写0.05还是0.016 (0.05/3)呢?  ...
