论坛老师好!
我用REST的Correlation ananlysis,voxel wise做功能图像与临床的相关,Groop image中input图像,seed variate中input临床因子的txt文档。
问题是:在结果图像中,以0.01为阈值(Threshold:2.70),差异区域的结果报告中peak intensity为什么不是大于2.70的绝对值,而是小数?是否这个值为相关系数呢?p值对应于一个相关系数的阈值,我发现类似的一篇文章(Spatial patterns of intrinsic brain activity in mild cognitive impairment and alzheimer's disease: A resting-state functional MRI study)中,做图像与MMSE的相关,列出了相关peak点的z值,那么这个z值是否可以由REST得到的peak intensity转换过来?
谢谢!

谢谢严老师!
我重下了新版的REST软件“REST_V1.8PRE_120905”,在GRF corretion这块,RUN还是红色的,请问是我下错了吗还是?

To 鑫迪:你把这个Fig也改一下,同其他GUI一致?
