Tue, 10/29/2013 - 06:47bonjovi_hou严老师，您好，我用新版DPARSF_A的Basic Version跑静息态数据，得到的Results文件夹里，有zFCMap_sub001_....nii格式数据。但在Rest软件"Add Group Images" 里输入结果时，提示“There is no data or non-data files in this directory, please re-select”。 去年我用DPARSF跑数据的时候，在Results文件夹里有.hdr/.img格式文件。...4624 reads

Mon, 10/28/2013 - 13:26zhoujun老师您好： 我用dparsf头动校正后，生成ExcludeSubjects.txt 文件，我想剔除几个头动较大的被试，我是不是直接删除头动较大的被试呢，然后继续后面的操作，还是需要其他处理？ 谢谢老师！6870 reads

Sun, 10/27/2013 - 11:27liuchen最近自己的一篇文章被PLOS ONE大修，方法学比较简单：一组病人与正常人之间ALFF自发脑活动的比较，数据的处理全部都是使用DPARSF进行的标准处理流程。 但是审稿人提了很多数据处理技术上的问题，鉴于自己的医学背景，望请各位高人指教，谢谢。 第一个问题：Q.2 The investigators excluded data that exceeded a specific motion threshold. However, it would be important to know if there...10603 reads

Sun, 10/27/2013 - 03:56bonjovi_hou请教一下，我在用DPARSF处理数据的时候，始终在Slice timing上报错，请见图片呈现的报错内容（见图）。我在2012年处理的时候，用同样的数据和参数处理没有任何问题，现在用的是Matlab R2012b和SPM8，请问这个是否会对处理程序有影响？多谢！3693 reads

Sat, 10/26/2013 - 11:35Authenty最近，我们发现疼痛敏感性的个体差异与楔前叶（precuneus）的灰质体积GMV异常有关（高敏感性个体GMV↘）。我们希望根据已采集的DTI，进一步检验与 precuneus 相连的白质纤维是否同样有结构异常。由于技术限制，我们目前打算只做FA与行为的相关分析，但是遇到一些问题，希望各位老师予以解答： 1. 这项研究的目的是探索目标行为敏感性的脑结构基础，如前所述，我们根据GMV结果选定precuneus为兴趣区，然后从白质FA的角度进一步 “验证” Precuneus结构差异的重要性（正在跑数据尚未拿到结果...4665 reads
