统计分析时cluster是否需要相加啊?

 各位老师好,我现在统计分析遇到几个问题,如下

Cluster 10

Number of voxels: 30

Peak MNI coordinate: 0 -15  60

Peak MNI coordinate region:  // Inter-Hemispheric // undefined // undefined // undefined // undefined // Supp_Motor_Area_L (aal)

Peak intensity: -3.3641

# voxels    structure

   30       --TOTAL # VOXELS--

   26       Frontal Lobe

   22       Right Cerebrum

   17       Gray Matter

   14       brodmann area 6

   14       Paracentral Lobule

   12       Medial Frontal Gyrus

   11       Supp_Motor_Area_R (aal)

    7       Paracentral_Lobule_R (aal)

    5       Supp_Motor_Area_L (aal)

    5       White Matter

    4       Cingulum_Mid_R (aal)

    4       Inter-Hemispheric

    4       Left Cerebrum

    3       Paracentral_Lobule_L (aal)

    3       brodmann area 5

cluster10里面SMA只有很少的voxl,但是在cluster11里面SMA的voxl大很多,请问我需要把两个cluster里面的SMA的voxl加起来吗?要是加起来,那么PEAK值用cluster10 的还是cluster11的?还有这个中央后回及SMA是只要报一侧还是两侧都要报?左右加起来一起报还是分开报。
问题有点多
谢谢各位老师的回答。
