老师您好,请教一个问题,我们在做功能连接选择ROI的时候,参照的文献中没有给出相应的坐标,只写了解剖部位,比如left and right OFC等,我们看到REST和DPARSF中均有 Predefined ROI from AAL template by selecting specific area 这个选项，不知该如何选择ROI，请老师指点。

是这篇文章,多谢指点!
"All 10 of these seed ROIs were created using parcellation units derived from the Harvard-Oxford Cortical Structural Atlas probability thresholded at 75%."
这是文章中确定ROI的具体方法。
Given the order in the original files were not easy to use in extracting ROI time series (e.g., the left right ROI share the same index), the ROIs were re-indexed as detailed in the {DPARSF}\Templates\HarvardOxford_Atlas_NewIndex_YCG.xlsx

Re: 功能连接 ROI选择的问题
文章中应该明确其确定种子ROI的方法。是否通过AAL模板？或者什么其它的方法？如果你仍然不能确定，可以把那篇文章列在这儿，我看看是如何确定的。

Re: 功能连接 ROI选择的问题
藏老师您好:
我也看到了,新版的DPARSF里有这个Harvard-Oxford模板来选择ROI，我想请教下怎么制作ROI来做FC的分析。

Re: 功能连接 ROI选择的问题
你好！DPARSF里面带的模板是这样制作的（http://www.restfmri.net/forum/node/1210#comment-1911）：

Re: 功能连接 ROI选择的问题
谢谢严老师:
我还有个疑问,我发现选择HarvardOxford-cort-maxprob-thr25-2mm.nii.gz 这个模板,不能再进一步选择其中的一个ROI,因为我只想做基于全脑FC分析,而不是几个ROI之间的分析,该如何进一步选择呢?

Re: 功能连接 ROI选择的问题
选了模板之后（选定multiple labels），会自动计算每一ROI的FC全脑map。然后选择你所需要的ROI功能连接图做统计就可以了。
