Dear Colleagues, 

严老师您好，我想问下猕猴112模板对应的ROI模板是什么图片，您能发我一下么。急需！感谢！

各位老师好，我采用dpabi的quality control对被试进行筛选，在采用90%的group mask进行了阈值为mean+2*SD的coverage threshold后，几乎把所有的被试都筛除了，请问这是怎么回事呢？？

Hi Dr. Yan,

I performed ALFF, fALFF, ReHo and DC by DPARSFA, starting from the directory FunImgARCW.

The input data of TR was 4 seconds by mistake, while the correct one should be 3 seconds.

My question is whether this incorrect input of TR would affect the final caculation.

Thank you in advance and best regards.

Hi. Eeveryone.

1. I was confused by the starting directory  while preprocessing ReHo. Should we start from FunImgARCW and check the "Filter" upon the option of  "Normalize by DARTEL " as shown in the ReHo.png.?

老师您好，

1 请问在DPASFA中用DownloadedReorientMats和Apply mats后，workdictionary里就不会生成QC和ReorientMats文件，对吗？

我的resting data 预处理时先是手动调整，发现workdictionary中会生成QC和ReorientMats文件，但是换成Apply Mats后workdictionary就没有这两个文件了。

2 如果某个被试的结构像不清晰，但是静息态数据头动在2mm范围以内，该被试的静息态数据还可以用吗？

谢谢老师。

Hi DPARSF experts,

I have two questions concerning the filtering step of preprocessing. When I run filtering before normalization, the origin coordinates are moved away from the AC for some of my datasets (when I check "origin" with SPM's "Display" button)--which negatively impacts the ensuing steps. I could still do filtering after the normalization but: (1) does this make sense? and (2) why could this change in the origin be happening? I'm using DPARSFA V4.5_190725 on Matlab R2018b.

Thank you in advance,

Adriana

严老师你好，在进行猴子的功能连接时出现报错如下图所示:

请问是没有配准么，怎么解决，感谢老师

各位老师，你们好：

我在用DPARSF进行预处理的时候遇到了一个问题：

实验数据大部分被试的slice number = 33，TR = 2s，然而在数据中存在一小部分被试的slice number = 38，TR = 2.303s，我想请问一下，这样该怎么处理呢？我可以将这个数据按照slice number = 33，TR = 2s和slice number = 38，TR = 2.303s分为两组然后分开进行slice timing步骤的处理，再将时间校正后的两组数据合起来进行余下的预处理步骤吗？还是说两组数据所有的预处理步骤都需要分开做呢？想请问一下这两种方式哪个是正确的呢？
