    各位老师怎么看Alphasim校正?是不是相比FDR不是那么被广泛认可呢?使用FDR校正得不到结果,如果使用Alphasim可以得出结果,这种情况下这样的结果可以报吗?

    各位老师好,本人神内医生,刚开始学做fMRI,看了DPARSF视频,有点疑惑想请教。 1、ReHo前不能先做smooth,但是detrend,filter要先做吧? 2、教程上似乎讲,ALFF/fALFF,Degree Centrality前不做Filter? 3、老版教程里FC前才需要做Nuisance Covariates regression,ReHo和ALFF前不用做;但新版的教程里似乎建议realign后就作这步,然后再做normalize等,大家一般接在哪一步后做呢? 4、...

    各位老师,   我在用rest看结果的时候会有出现异常增强或减低的voxels不在灰质上,在白质上,预处理的时候也是default mask,应该在哪一步如何做来去除这个因素。或者两样本t检验的时候将白质脑脊液成分做协变量?谢谢!
