SPM8自带的VBM，我是按照John Ashburner的VBM Tutorial一步一步实现的。即New Segment->Run DARTEL->Normalize to MNI，

VBM8的Estimate&Write也可以进行VBM分析，得到分割后的图像。

我看文献里说使用VBM处理过后的灰质图像或者白质图像，那这个白质图像是指的SPM8处理后的smwc1*图像，还是没有经过smoothing的mwc1*图像？又或者是VBM8处理过后的m0wrp1图像呢？

Dear Dr. Yan,

Hi, I'm doing a research about difine several ROIs in a small region, such as PCC, and try to compare the releationship with eachother.

considering  the distance is close, I'm not sure the releationship is true or just because of the smooth to make these neighbor ROIs have similar activity.

do you think it would be help if I skip the step of smooth when I do the proprecessing?

thanks a lot!

Dear Dr.YAN

can i use FDR correction for two sample ttest output?

Thanks for your help

Dear Dr.YAN

first i got these features(ALFF.fALFF,ReHO and VMHC)

I did tow sample ttest for 70patient and 70 control using  depabi and got the statistical map as .nii pecture ,then i used depabi viewer to show the significant regions for this map with template AAL, my question how  can i map these features to these regions and how can i find  all significant regions (regions affected by these features) for all slices.

Thanks for your help.

Dear ChaoGan,

Because I don't have the latest version of matlab, so I use the matlab 2011a, spm8 and dpabi4.1 to do the preprocessing, this is the Error:
