关于Cl. Report体素大小问题

Submitted by luohaha on Tue, 09/29/2015 - 17:11

 老师，你好。您说Cl. Report中的体素太小（如9  Left Cerebellum， 9  Declive， 9  Cerebellum Posterior Lobe，6  Sub-Gyral，5  brodmann area 18，2  Occipital_Mid_L (aal)）需排除，不用汇报进我们的实验结果中，但究竟体素多小时才需要排除掉？有什么标准么？

Cluster 1
Number of voxels: 112
Peak MNI coordinate: -45 -78 -12
Peak MNI coordinate region: // Left Cerebrum // Occipital Lobe // Middle Occipital Gyrus // Gray Matter // brodmann area 19 // 
Occipital_Inf_L (aal)
Peak intensity: 17.5958
# voxels structure
112  --TOTAL # VOXELS--91  Left Cerebrum
75  Occipital Lobe
68  Occipital_Inf_L (aal)
54  White Matter
40  Middle Occipital Gyrus
34  Gray Matter
27  brodmann area 19
21  Inferior Occipital Gyrus
20  Cerebelum_Crus1_L (aal)
16  Temporal Lobe
13  Fusiform Gyrus
12  Fusiform_L (aal)

2  Occipital_Mid_L (aal)

我们通常不需要报告这么详细的信息。这个cluster共有112个体素，其中绝大部分位于枕叶，但延伸到了小脑，报告的时候，可以说在occipital lobe (extending to the cerebellum)。至于延伸到小脑这一小部分，到底是什么原因，这就很难说了。

 老师，您好，我的问题是：1、用slice viewer中的Theshold by cluster size应该怎么设置clusrer sizer的大小呢？有教学视频中说不知道怎么设时敲入SPM—Criterion就知道怎么去设置，但在什么地方敲入SPM_Criterion呢？我尝试在MATLAB中Command Window中输入这个，但提示错误；2、我做的静息态ALLF时设置Cluster size>30,rmm=5，P值为0.05，但Cl. Report中几个激活体素都很小，结果如下中的Cluster 1，那些较小的激活体素我是不是就不应该纳入我的文章报告中呢？然后大小为多少的体素我才需去考虑纳入？这些纳入标准是什么。

你设置的阈值是30个体素，那么，这些clusters都在30个体素或以上。你报告每个cluster的时候，只需要报告每个cluster的总数。脑区名称，则可以不止一个（比如hippocampus, extending to the amygdala）。
