所谓结果的可靠性，可以从组水平和个体水平看判断。 ReH
ReHo方法，对于一个个体的数据，很难说结果是否可靠。对于一组数据来说，我们通常可以做一个单样本t检验，以检验全脑中哪些脑区的ReHo值明显高于全脑均值。一般会发现，defualt mode network的脑区的ReHo值会明显高于全脑均值，并且在全脑中，这些脑区的ReHo值差不多是最高的。这种情况下，可就认为这组数据是可靠的。
如果是functional connectivity，可以选一个个体的数据，预处理后（包括空间平滑），选择PCC的一个ROI，functional connectivity结果通常会显示出较好的defaul mode network。这个标准，可以初步做为判断个体数据可靠性的方法。
组间或condition之间的结果，一般不可以用于检验数据的可靠性。至于与以往结果是否吻合，那要看情况。“难以解释，就不可信”，是不可信的。
谢谢臧老师的解答，我用的是ALFF方法，发现结果很散在，象噪声，我会再试试另两个分析方法的。
Reho报错
根据REST的使用说明，选择数据，MASK选的是BrainMask_05_61x73x61，报错内容如下，请问该如何办？

Re
请检查一下REST的安装是否有问题。
ROI分析
Re
然后做相关即可。
Roi
Re
仔细看一下Slice 64 到Slice 71，动手试试就好了。
另外，可能在这个月会出Course的第二部分，把提取时间序列部分再单独说说吧。请稍耐心等待一下。
提取协变量时出错

请问是哪个步骤做错了呢？
