Fri, 06/14/2013 - 02:52Chen0075各位老师, 有个VBM的问题, 在做VBM的modulation时候我们经常这样选择： 单击Modulated normalized选择“affine+non-linear only”。这里的affine+non-linear only是什么意义，是说T1像经过affine和non-linear两次normalization，然后得到一幅MNI的图像？ 在DPARSFA的VBM里面是如何选择normalization和modulation过程的。 谢谢！2951 reads

I am a bit surprised at the results because the z values of my maps are pretty low (most are between -0.6 and 1). I did not globally regress my...8818 reads

Wed, 06/12/2013 - 23:53YAN Chao-GanDear all, Here is a conversation long time ago on the necessity of removing linear trend before filtering, if we think linear trend is a kind of noise. Hope this information is helpful for some of us! P.S., whether linear trend is meaningful or not, @WANG Xin...6806 reads

Wed, 06/12/2013 - 14:23qqguai老师，请问下：低频的 scanner drift 可以在滤波的时候被抑制，为什么之前还需要对它进行 nuisance covariate regression 呢？ 是否回归这一步是为了减弱它对其它频率的影响。。。？ 谢谢！5584 reads
