最近看文献，只知道vbm经过modulate后是volume，不经过modulate是的density，不过具体表示了什么还不是很清楚。而且为什么经过modulate就是体积也不是太清楚。下面一段话是文章中的，没太理解，请指点下，谢谢。还有，用哪一个指标比较好也没有具体的说法吧（体积还是密度？），是不是喜欢用哪种就用哪种？有没有什么经验呢？

I have used SPM to preprocesses my data before using the REST utility to convert the data from .nii to niftiPairs. But I am now running into problems and I receive errors and warnings in many of REST's tools about the dimensions of my images. Here are all the problems I've encountered:

Dear all, I would very much appreciate your help with the following:

各位老师好！我想用被试的T1结构像做模板底图，不过不想要头皮，只想显示脑的结构，该怎么处理呢？REST或者别的软件有这个功能吗？谢谢！

Dear REST experts, Thanks for your recent works, REST-GCA :)

Hello, I'm attempting to perform a Paired T-Test on the functional connectivity of two resting state conditions within-subject. I have a Placebo run and a Control run for the subject. First I converted my .nii files to nifti pairs using REST's conversion utility. Then I used the Functional Connectivity tool to create a FC and zFC Map for each condition individually using the same ROI location. Then I placed the zFC maps into their own folders (I have 1 folder for the zFC map from the Placebo run and another folder for the zFC Map from the Control run).

您好： 我用ReHo对我的数据进行分析，预处理利用REST工具包进行，统计分析two sample T， 发现达到阈值的结果很多在脑壳外面(MRIcro+Che2bet模板)，请问为什么？ 这样会不会把有用信息剔除掉？对于脑外的部分如何处理？ 谢谢

大家好！11月22日（周二）晚上七点的组会由研一学生原彬科汇报。汇报的内容是三种配准备方法（SPM2-type,SPM-DARTLE,HAMMER）. 附件是汇报会涉及的两篇文献。第一篇涉及到了前两种方法，第二篇涉及到第三种。有兴趣的老师和同学可以参看。 与参加组会的同仁可以于晚上6点50分通过Skype呼叫 wenbinjia.08@mail.com，这样就可以通过语音参加组会了。

Dear all, Thanks for your nice softwares. I am using DPARSF. I can't have the pictures for checking normalization. Insted, I have got a warning.txt file that says : "Since Image Processing Toolbox of MATLAB is not valid, the pictures for checking normalization will not be generated.\n" Does it mean that I need this Toolbox of MATLAB to have pictures for checking normalization ??
