Thu, 09/01/2011 - 14:17liufeng我要做two-way repeated anova，又把每个人的GM map作为了协变量。 rest软件能做把GM整个map作为协变量，但是只能做one way anova，而且rest软件不能做repeated anova。貌似spm软件虽然能做two-way repeated anova，但是不能把整个map放进去作为协变量，只能放进去年龄、性别等这种covariate。 所以我想问下，我要做two-way repeated anova（不是two-way anova), 还要把GM map作为协变量，...5707 reads

Thu, 08/25/2011 - 04:57yhcha@mednet.ucla.eduDear Rest MRI Forum, I have recently completed a PET scan study between a patient group and controls and have computed some ROIs which are more active in the patients or more active in the controls. I'd like to see whether these ROIs are functionally...9414 reads

Wed, 08/24/2011 - 13:15stevenlee697严老师您好，我是一名初学者。现在欲进行默认网络的功能连接研究，阅读了一些国内外相关文献，发现绝大多数中文文献ROI的提取用直径6MM的小球，而外文文献（如Abnormal Brain Default-Mode Network Functional Connectivity in Drug Addics）是对研究样本时间序列（非任务）计算后生成的，并做了检验。我想除了这两种方法以外，是不是还有一个固定的标准化后的默认网络ROI（MASK），后两种方法较第一种更准确，但后两种方法之间有无明显差异？...12627 reads

Wed, 08/24/2011 - 08:31liq2005liq严老师 你好 在你上次教了我们如何使用CARET之后，我就一直想尝试使用它，但是一直没有成功。我按照你们网页上介绍的把caret_distribution_Linux32.v5.64、那个TUTORIAL文件夹、以及两个你为我们做好的.spec,.scene文件，并把WINDOWS的区域语言选项中高级项的UICODE选为英文之后重启。CARET文件可以打开，我按照你所讲的步骤一步一步地把激活结果文件叠加到大脑表面结构上，但是无论我选择任何按键，我的激活图始终显示不出来。甚至，...8141 reads

Tue, 08/23/2011 - 17:27meilingrui严老师： 您好，我看了你的教学视频，关于ANOVA这部分有些问题不是很清楚。 我现在做的是三种针灸方法之间的比较，有任务的，也有观察针灸之后的静息情况的，我想问一下： 一：是不是做任务的三种之间的比较也要先计算ANOVA 激活的区，用这个mask去看两两之间的配对T检验呢？ 二:我试了一下，用ANOVA之后算出来的激活区，很小，如果用这个做mask的话，后面的两两比较几乎就没什么激活点了。 三：...6306 reads
