在两个mask内单独矫正 VS 合并mask后再矫正 的方法问题

我要做灰质体积与行为指标的相关,根据已有理论,我欲分别考察两个系统的灰质体积,一个是DMN系统,一个是Pain Matrix系统(使用WFU自己作的mask),已经有了这两个系统对应的2个mask。结果,如果在全脑上进行矫正,很多假设中的区域不能过矫正,而那些相对最强的cluster又与假设很契合,因此希望在这两个mask内来做矫正(PNAS上采用这样的处理办法)。

如果我希望在一篇文章中分别回答这两个系统的灰质体积是否与目标行为相关的话,

1.1 我在迟疑究竟是否必须把两个mask合并,然后在更大的mask内做矫正,这样的话,有几个预期中的cluster就不能存活。请问我能否分别进行两次计算,在每个mask内做矫正?
1.2 如果可以的话,矫正方法是否必须相同?

Hi,
I'm trying to run some functional connectivity analyises on the ABIDE data by using DPARSFA and, just after applying the Reorientation Matrices (downloaded from http://www.restfmri.net/forum/DownloadedReorientMats), I get the following error (pasted below)

请问什么是卷积和去卷积?

 能否用通俗的语言讲解一下,本人非理工科背景

Challenges of meta-analysis on resting-state fMRI studies

    Activation likelihood estimation (ALE) is a very good method for task fMRI meta-analysis studies (including both within-group between-condition activation difference and between-group activation difference).

template in spm

 Hi, 

As we know, there are two templates in spm: East and European templates. I want to know where (directory and file-name) these two templates are included in spm folder, because I want to do a comparasion between them. could you tell me that?

thanks! 

rest的FC做完之後的影像數目錯誤

 老师,以及各位先进:

我使用rest的functional connectivity作Voxel-wise的FC之后,发现我preprossing的资料原本有170个档案(一共约80mb)
出来的zFC却只剩下大约1mb大小的一个档案,同时我的matlab window出现这些警告
 
Computing functional connectivity with:"C:\import\20130927\Analysis\FunImgNormalizedSmoothedDetrendedFilteredCovremoved\pd_004pre"
 

Widespread correlation of resting state activity after entering more subjects

Dear DPARSFA and resting state experts,

viewing DPARSF results

Hi

I have done done FC Analysis along with ALFF. In SPM i usually get a matrix, which you can view after clicking 'Results' and rendering brain image over it. Is there a similar way in DPARSF to view results in pictorial form ?

Thanks

请教一个关于新版DPARSF生成的zALFFMap和老版本生成的mALFF-1的区别的问题,谢谢

各位老师好
新版DPARSF生成的zALFFMap、zfALFF和老版本生成的mALFF-1、mfALFF-1的区别的是什么那?对于结果会产生什么影响哪或者说应该怎么选择取舍哪?谢谢!

默认网络模板

谁有默认网络的模板啊,SPM里面怎么没有啊!!!求助……
