dpabi-VBM处理相关问题

Submitted by Yuanyuan on

严老师您好!

1、我已经用dpabi的做了resting state fMRI的预处理,现在准备用dpabi的VBM分析灰质体积,我用一个subject用默认参数试跑了一次(只勾选了Reorient T1*和New segment+DARTEL以及Default mask),出来的结果文件目录和fMRI预处理生成T1ImgNewSegment同一个被试名下的文件相同。我有两个问题:

①请问用dpabi VBM跑出来的T1ImgNewSegment结果和fMRI预处理生成T1ImgNewSegment是否完全相同呢?能否直接用fMRI预处理生成T1ImgNewSegment里面的内容来进行灰质体积分析呢?

②在试跑这个subject的matlab流程里有一项是Running DARTEL: Normalize to MNI space for VBM. Modulated version With smooth kernel [8 8 8],也就是使用默认模板的时候smooth kernel自动设置为8 8 8,请问意思是这个平滑核是不能调整的吗?

DPABISurf Two sample T test

Hello teachers!

I still can not use PLAM when analyzing FC in ROIs,in DPABISurf Viewer,I have results if  the P value is equal to 0.05,but no one in the 0.01.

Can I report this kind of results?If I only focus on the default mode network in both volume and surface space ,how to deal with it?Or ueing the mask of Yeo 7 networks is enough?

Thx a lot.

ALFF/fALFF/ReHo using DPARSF

Submitted by FaezeVedaei on

Hi 

I have a trouble uploading the data direcoty on DPARSF for doing some processing. Even though I watch the course, I could not get why I can not upload the direcoty and have the list of subject's folder in the assigned window. 

At this time I have all preprocessed rsfMRI data and just want to get ALFF/fALFF/ReHO stuff. 

Can you please let me know first of all if I can you DPARSF for just this purpose with not doing preprocessing and just ALFF/FALFF/ReHo stuff?
