Besides, you can also use SliceViewer of REST to get specific area mask from AAL:
SliceViewer -> overlay -> AAL -> click mouse to the area you want -> click button 'save2mask'.
My fault, for the most recent version (REST_V1.8_130303.zip) of REST, you could use 'reslice image' to resample your mask.
For the most recent version (REST_V1.8_130303.zip) of Slice viewer, you may need to uncomment line from 4011 to 4015 to enable saving cluster from AAL or Brodmann.

请问这个怎么解决啊？需要怎么重采样啊？谢谢各位了~~

Re: 请教一个关于mask的问题
The resampling is an old question in this forum, which got a lot of solutions.

Re: 请教一个关于mask的问题
非常谢谢老师，但是我刚刚试了一下，现在主要存在这样一个问题，即使我用slice viewer制作AAL的模板的时候，我按照AAL模板中感兴趣区域所对应的的坐标输入，然后鼠标指向了该区域，然后点了save cluster,但是这样出来的效果是把所有的区域全保存下来了，所以想请问老师是不是我步骤上有不对的地方？那个P值和cluster大小需要怎样单独设置么？非常感谢老师~~~

Re: 请教一个关于mask的问题
非常谢谢老师，我刚刚安装了1.8版本的rest，但是针对第一种方法，当时我就是利用重采样，想保证WFU做出来的mask和即将提取灰质体积的模板一致，所以在重采样时，一种是直接重采样3*3*3，一种是选择了61*73*61的mask进行匹配采样，但是这样做完的结果就是出现一开始那种情况，仍然是mask不匹配，所以我想请教一下老师是不是当用rest提取灰质体积时默认的mask是基于什么模板的，为什么老师会出现精度不匹配呢？
针对第二种方法，能请教老师具体这个取消语句在哪儿操作吗？实在不好意思，打扰老师了~~

Re: 请教一个关于mask的问题
过一遍Course Part II.
选好你的参考像（目标精度），即你某个被试的灰质像。
