FC map problems

 Hi experts, 

underlay如何调整和overlay一致

严老师:
    您好!我的underlay解剖图像和overlay的功能图像大小不一致,无法重叠成一张图,应该怎么来调整成一致呢?谢谢

关于去除前10个时间点

严老师:
      您好。
      最近有个reviewer对我文章中去除前10个时间点这一步骤提出疑问,说:It seems odd to disregard the first 10 acquisitions。我看了下国外文献似乎很少有去除前10个是时间点的。请问除了回答说这一步骤是为了“the signal equilibrium and participants' adaption to scanning noise‘,有没有相关文献支持这一步骤?
     谢谢。

Questions on Normalization and Reorient in DPARSF-A

老师们好。

近期,学习dparsf的新版与旧版的视频。
由于学生是新手,遇到些问题,论坛上也没有找到具体的答案。故还是冒昧地发帖子请教。
如有不妥之处,也请批评指正。先谢谢了:

1.Normalization这一步骤中,旧版的dparsf 如果将"采集到每个被试的T1像时,用T1像的联合分割方法,把功能像配到相应的T1像中",只需要填好这些参数normalize;bounding box; Voxel size; Normalize by T1 image unified segmantation.; east asian 或eurpean,即可完成。

ROI-wise Functional Connectivity in REST

 Hi, I just finished running a functional connectivity analysis using the REST toolbox. I am looking at the FC between 2 regions so I entered those as ROIs and chose ROI-wise analysis.

The output is a series of txt files and I am wondering what exactly the numbers in the txt files represent? I am guessing that:

mask制作问题

老师们,好。

近期看到一篇文章: Resting-state functional connectivity patterns predict Chinese word reading competency. PloS one, 7(9), e44848
里面提及的mask制作,此文是这样说:
The  RSFC  analysis  was  performed  using  the  Resting-State fMRI Data Analysis Toolkit (REST) [25]. We conducted RSFC

Mask does not match?

向各位老师请教一个问题啊:

         用DPARSF_V2.2_130309 处理数据,在进行了slice timing;realign;Reorient Fun;Reorient T1;T1 coreg to Fun;New segment+DARTEL;Normalize 之后,准备进行接下来的步骤:Nuisance Covariates Regression;Warp Masks into individual Space等

Reorienting matrices for online data

 Given the amount of time and effort for interactive reorienting, here we release the reorient matrices for online data of Autism Brain Imaging Data Exchange (ABIDE) (Di Martino et al., 2013) (fcon_1000.projects.nitrc.org/indi/abide/).
