Nuisance Covariates regression 应在Normalize 之前还是之后?

Submitted by doctorsol on

想请教一下各位老师,Nuisance  Covariates regression 应在Normalize 和smooth之前还是之后?因为在Dapbi基础版中默认的是在最后做Nuisance  Covariates regression,而在高级版中又是在Normalize 之前做,所以感到很困惑?

DPARSF for multi-slice data

Submitted by David on

Hi,

is it possible to use DPARSF for multi-slice data? As I understood, it is necessary to input the exact slice-timings in ms for slice-timing correction. However DPARSF only allows for the specification of the slice order. Is it maybe possible to just enter the slice-timings in the slice-order field?

thanks for the help.

 

纹状体种子区分割问题

Submitted by YinLu on

老师您好:

        很抱歉打扰您了,我在使用fsl的组件first进行分割纹状体种子区时遇到了一个问题,我是想把壳核(Putmen)进一步分割为背后部(dorsoposterior part),腹后部(ventroposterior part),背前部(dorsoanterior part),腹前部(ventroanterior part)共4个分区。文献给出的方法是根据y=0,z=0轴作为边界分割,我想请教一下您怎么用first分割,官网里面没有具体的描述,谢谢老师!
