Hi. Professor Yan

I got two questionas about task fmri data preprocess and first level analysis.

1 There was two kinds of task with four runs for my data. In the preprocessing, should I preprocess the data one run by one run, or one task (two runs) by one task, or four runs together?

2 For the first level analysis, is it necessary to add WM and CSF signal as covariates？ If so,  how do I get WM and CSF signal in the preprocessing?

Look forward to your reply.

老师您好，我已经run好几个小时了，没有报错，但是并没有新的文件生成，每完成一个预处理过程都要生成新的文件吗？？MATLAB也没有新信息出现，请问是什么原因呢？？

1.请教下各位各位老师，做任务态的功能连接前如何回归掉任务态回归子？具体怎么操作呢？

2.是否需要区分block设计和event-related设计？

3.如果希望观察任务本身对功能连接的影响是否还需要回归掉任务态回归子？

严老师好，各位老师好。我在使用dpabisurf做预处理的同时，想要使用freesurfer生成的皮层下体积统计数据来进行统计，可是在\Results\AnatVolu\文件夹里并没有Anat.segment~~.tsv文件。请问是因为版本的原因还是我勾选得不对呢？或者说这个文件在其他文件夹里？麻烦各位老师指导一下，谢谢。

Dear professors:

 we are confused about the following question raised during Slice-timing.

Version: DPARSF 5.1, advanced edition

**Question1: Is it really feasible to paste Timepoint of slice order into the array of "Slice order" like in SPM?

Respcted Yan, and all,

When I use DPARSF to calculate the functional connectivity of the preprocessed data of the HCP dataset(rfMRI_REST1_LR_Atlas_MSMAll.dtseries.nii), it always prompt the error:

Hi Dr. Chao-Gan

I have been using DPABI for resting state fMRI , and ALFF measurement on the groups of subjects. I just wanted to do some statistical analysis on the groups including 1-sample, 2-sample t-test and ANCOVA.

I just see on your manual paper that you refered to SPM and REST tools for doing that.

Can you please clarify me what is the tool I can that, as I see DPABI has this tool too.

Thank you very much
