1. 用SPM完成预处理步骤，想用DPABI完成CSF、WM、头动的nuisance removal，文件夹应该如何排列？整个过程中用到了什么文件？
2. 在http://www.rfmri.org/comment/3173#comment-3173中推荐Remove Covariance--> ALFF computation --> Bandpass filter 的计算方式，用DPABI操作时候设置如下：

Dear Experts,
I have encountered an error in DPARSFA that seems related to slice timing. I found another post, which suggested that slice order may be problematic (http://restfmri.net/forum/node/516).
Dear Dr.Yan,
Last time when I preprocessed the resting state data, the PictureForChkNormalization showed some strange pictures.
Dear Dr. Yan,
I am sorry to bother you that if I correct head motion before using DPARSFA, will it affect the result of head motion? Because when I use two different ways, to be more precise, I use head motion correction before and after realignment, the results of exclude subjects according to max head motion are different. The result of head motion correction before realignment manully is excluded according to DPARSFA, but raw data without head motion correction is not.
Dear Experts:
I'm trying to preprocess my data using "DPABI " and facing the following questions:
Dear Experts,
When I clicked "DPARS 3.1 Advanced Edition", I encountered the following error:
Dear Chao-Gan,
I have read some ALFF papers, and found that only ALFF with positive value was shown in the statistical map of one-sample t-test. Does ALFF with negative value make no sense? If so, should I use the mask containing voxels with positive value while analyzing data?
Thank you in advance.
Best,
Vincent
Dear all,
I was considering about the possibility of perform a REHO analysis inside different masks (RSN masks, like DMN)
For example, in the step default mask/No mask/ user mask. introduce the DMN mask and then run a REHO analysis. Will I obtain the activation inside this mask only?
It has sense? or I'm double dipping the data!
Thank you so much!
