    严老师您好!我想问一下,使用DPARSFA做预处理,发现标准化完成后的图像都有小黑点,这种情况是什么造成的?以及该怎样解决?

    Hi, I would like to know whether the Degree Centrality calculation is based on positive correlations only, or also on negative correlations? If I set a correlation threshold of r=0.2 will it take the absolute values of correlation and include negative...

    各位老师 您好   在计算功能网路时,点选ROI wise后,放入ROI 我想问是否有方法将多个ROI放入一个NII档案, 然后REST读取此NII档案,可以顺利读取里面数个ROI 可以不用手动输入多个ROI到 ROI List 谢谢

              各位老师,大家好!本人初入大脑结构功能网络研究这个方向。之前有一批结构数据已经用explorer dti做完了预处理,现在接下来要计算结构网络的各项物理参数比如rich club系数,小世界特性等等。不知道哪位老师处理过结构数据,可否分享一下批处理操作过程。本人不胜感激!在功能网络论坛请教结构网络内容,冒昧打扰,还望老师们谅解!

    老师您好,当用dpabi做统计分析时,当添加同样维度的mask时,会报input  too  many arguments的错误,当不添加mask时,就不会报错,但是permutation  test会报错

    尊敬的严老师:       您好!最近处理一批fmri的数据,每个被试的TR不一致,有2、2.1、2.3等等,在进行到slice timing这一步时如果上一个被试与下一个被试TR不一致程序就会自动停止。我按照之前授课视频将TR设置为0自动检测TR的做法,但是matlab总是报错。希望老师能给予解答,谢谢老师。(DPARSF 4.3 basis,spm8,matlab2010b)
