Sat, 01/22/2011 - 20:28luojia请教一个关于矫正的问题,我做的课题是患者治疗前后的比较,采用了配对T检验,检验时采用了FDR矫正,P值取了0.05, extent threshold为10,结果为阳性,有存活的VOXEL,但在接下来的SLICE VIEW时不知道该如何选择CLUSTER SIZE,是选择10吗?还是其他的?是不是就不用再采取AlphaSim矫正了?谢谢91390 reads

Mon, 01/17/2011 - 16:08xying5158您好,我用dparsf得到alff结果进行两样本t检验时发现还有脑室内的信号增强还有很多undefined的脑区(自己做的mask和brainmask均有),这时候应该怎么处理? 另外,利用两组数据单样本t检验结果做mask的表达式是不是(i1>0)+(i2>0)>0,用~表示不等于 image calculator出错,求准确表达式 不胜感激!92331 reads

Sun, 01/16/2011 - 15:28bgao老师们,你们好! 非常感谢你们对我以前问题的回答!现在我又遇到了问题,特来求教。问题如下: 问题一:我想先确认一下几个问题: 1,我们用restsliceviewer 看图像时,把十字架点位到一个点后,这一点的ReHo值是不是montage左边的值?如value:Underlay/overlay=43/14.325 这一点的ReHo值是不是14.325? 2,我们用rest做单样本T检验时,用的smReHo数据,这个是每个image没减去1的,把Base设为1,...93051 reads
