Global signal correction

Hello,

DPARSF allows for the regression of the global signal. This correction is known to be problematic and I wonder if, in a near future, DPARSF could allow more sophisticated corrections such as the CompCor method (Behzadi et al., Neuroimage, 2008).

Best regards,

FunImgARC中又出現了以下ERROR

在跑到FunImgARC中又出現了以下ERROR

??? Index exceeds matrix dimensions.

请问做FCD时,该软件计算的是gFCD还是LFCD?

 老师好,我刚刚接触functional connectivity density(FCD),看了一些文章,FCD有global functional connectivity density(gFCD)、local functional connectivity density(LFCD)、long-range functional connectivity density(long-range FCD)想问一下,rest1.8中,得到的结果是那个值?LFCD和臧老师提出的ReHo有什么区别?谢谢

如何找个人的ALFF的活动强度值,或是功能连接强度的值。

 老师,
 你好!我做完了 ALFF 与MMSE 的连接,发现了比如有PCC与MMSE成正相关,此时如何能找到个人的PCC的ALFF 的那个值呢。因为我看别人都会再做个线形图,横坐标是MMSE,那纵坐标的,即每个人的,怎么找呢?
  谢谢!

rest当中采用alphasim校正的疑问

老师,您好!
         看完视频后,有几个疑问想请教下。
         1、发现alphasim校正当中需要设置FWHM。我做的是功能连通数据统计结果,但是在预处理步骤当中没有做smooth这一步,那么还可以采用alphasim校正么?如果可以的话alphasim操作界面当中FWHM应该如何设置?如果不可以是不是得重新进行处理补上smooth步骤(流程为DPARSF功能连通的标准流程,只是少了smooth步骤)?

Detected 0 timepoints DPARSF

 Dear All,

I encountered a problem when using DPARSF to process the data. The program says it detected 0 time points for most of my data....I double-checked my data, they were converted correctly and the directory, etc. are all correct.

关于功能连接结果的疑问

老师,
      您好!
      我在做功能连接得到如下的结果:

DPARSFA error

Hi All,
I am getting this error when using the DPARSFA. Any help would be greatly appreciated.
