关于voxel-wise的问题

Submitted by 小皮蛋 on Sat, 07/09/2016 - 15:11

老师，您好，我用一个AAL脑区作为ROI进行voxel-wise分析，定义好了ROI之后运行会报错，不知道是什么原因呢

问题不是非常明确，只选择了AAL一个区域（范围）作为种子点吗？请问核对了种子点nifti图像的完整性吗（或者说可以正常读取吗）？

是只选了一个脑区做种子点，用rest定义了ROI之后，点view ROI就会报错，

??? Error using ==> rest_misc>ViewROI at 310
Wrong ROI definition, Please check:

但是我是按照视频上定义BA的方法定义的AAL模板ROI，不知道为什么会出错

可以在rest sliceviewer界面overlay上AAL模板（比如61 71 61的），然后再保存相应的ROI。那个问题可能是ROI格式不对。

我就是overlay选的61*73*61的AAL模板，underlay不用选吧？然后选择set range of threshold，在下面的框中填上脑区对应的数字，最后保存cluster。但是保存完了点击view ROI时，就会报错。模板选的是rest里面重采样好的，请问问题可能出在哪里呢？谢谢了

还有一个建议，先保存AAL模板上的区域，保存好之后再用reviewer打开检查一遍，核对没有问题后，在FC分析中以这些种子点“+mask”的方式加载。
