VMHC处理问题

Submitted by Jianglan on

严老师好,最近在处理VMHC的过程中遇到了几个问题,希望您能解惑:

1.是不是因为要制作组内T1对称的模板,所以必须所有数据一起处理?如果因为内存问题,我能不能分批次处理,那么要从具体功能核结构的哪个文件夹一起保留呢?同时还要保留哪些文件夹?

2.因为要用到对称T1模板,所以健康人和患者的数据是不是要分开处理?然后组间分析的时候制作mask是要用健康和患者的对称T1mask一起取并集么?

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?

We modified the parcellation in GraphVar 2.02 and added in house rat brain atlas. Everything seems fine up until final stage of exporting. We think it might be callback of different atlas (human) but not sure. We are using Matlab 2017a. Here is the error message. Thank you for any help you can provide:

 

How to deal with behavioral variables correlated with mean framewise displacement (FD)?

Submitted by guiziwu on

Dear all,

As the requirment for resting-state fMRI studies on controlling head motion is becoming stricter and stricter. Typically we have to use a more stringent criteria to exclude participants for the head motion. For example, conducting scrubbing in the preprocessing and excluding participants who have large mean framewise displacement (FD) (e.g., FD > 0.2, 0.15). And we also need to make sure that our behavioral variables are not correlated with the mean FD, to convice the reviwers that our results are not influenced by the head motion.

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.
