请问用dpabi的viewer同时打开多个img时那个Overlay按钮的作用是什么，能像xjview那样显示多个img的共同激活区吗？

Dear all
Hi

How could extract functional conectivity of my rest fmri data using DPARSF?
Do you know any thing about calculating eta2 value and similarity matrix ?
many thanks in advance.

Hi every body

I am new in using dpabi, after downloading dpabi and set matlab to add with subfolder and run dpabi I always get this error message:

Dear all,

Is ReHo value equal to Kendall's W (KCC)?

And if we use a region to be a ROI and extract its value, then this value is ReHo value or KCC value? (Some values are more than 1, so KCC can be more than 1?) 

Your help will be greatly appreciated!

Best,

Dear all,

DPABI V1.2 is on its way. However, I don need your help now. 

Please take one minute to click this link (https://www.missionmainstreetgrants.com/business/detail/7733) and vote for us. (There will be a small survey, but you can skip it by clicking "no thanks" at right-bottom of the page).

Hi! Dr.YAN

I am doing a degree centrality study with the help of Dpabi.

Significant and desired group difference have been found, if we do not regress out the GS.

Different threshold for connectivity (0.2;0.3;0.4) and scrubbing or not have been used to test the effects of preprocessing options on the results. Group difference are stable.

Yet, GSR(Global Signal Regression) dramaticlly changes those results. We can not find similar results even using the ROI method.

Hi, Chao-gan

I found that DPARSFA could not identify 4D  files in pairs(.hdr, .img). It only identify them as one time point. It maybe not convenient for someone who want to use DPARSFA to do data processing of   4D  files in pairs(.hdr, .img). Should it be a bug?

Whatever, I just let you know this phenomenon. Thanks.
