GCA结果会随ROI增减而变化

Submitted by 李川0810 on Fri, 02/27/2015 - 17:55

老师：
您好！最近本人在做GCA时采用DMN网络ROI的结果与加入一些其他脑区的结果有一些差异，不知道这样的结果是否正确，在计算原理上是不是应该不受脑区的个数而影响？并且在GCA的结果中经过t检验后，其负值的意义是什么？
期待您的指导回答，十分感谢！

rest_spm_slice_vol.mexw64: access is denied

Submitted by newsoul on Sun, 02/22/2015 - 03:36

 Dear rs-fmri experts,

I am trying to use REST to do functional connectivity analysis, but when I just pressed the "run" button, it reported an error: 
??? Invalid MEX-file
'F:\REST_V1.8_130615\rest_spm5_files\rest_spm_slice_vol.mexw64': Access is denied.

Does anyone know what cause it? Any ideas?
