    There are so many regions and these regions appear to potentially align with networks. Data reduction strategies may aid in streamlining the many results reported here. 有个reviewer给我这条意见,一头雾水,这该咋整呢?

    老师们好,我在投稿的过程中遇到些问题,想请教下。 1) reviewer说臧老师在2004年的ReHo的第一篇文章中,smooth是在计算ReHo之前做的,现在改到之后做,原因是什么? 2)我做了全脑的Voxel-wise的相关性后,选了ROI做了相关性,reviewer认为在没有先验假设ROI的情况下,做ROI-wise是错误的,会增加统计学错误。奇怪,我看别人的文章似乎都是这么做的。但是我改用ANOVA的voxel-wise的结果做了MASK,结果也比ROI-wise的结果更加符合我的假设。 3)...

    请教一下各位老师们 为什么我用Dprasf 预处理后图像在脑底部出现黑色条带(见附件),而用其他方法预处理则没有出现?是否可以通过修改dparsf的处理过程得到改善,这样的结果对后面的分析会产生怎样的影响? 非常感谢!
