关于rest进行gca与spm进行dcm提取roi方法的比较问题

Submitted by taofly on Mon, 10/21/2013 - 10:26

严老师：
       您好！我用rest做gca，提取roi那步选的提取小球，它是通过平均小球内的体素得到的时间序列。看到不少文献说gca和PCA主成分结合的方法更好，于是尝试着将平均换成提取主成分的时间序列，效果不好，贡献率都太不集中了。请问您是否也考虑过主成分的方法呢？

question about more details for the FC behavior correlation

Submitted by jane on Sat, 10/19/2013 - 00:46

Thanks!
