PhD Positions in UNC-Chapel Hill
Three PhD positions are available, with one for each of the following research directions, in the IDEA lab of UNC-Chapel Hill, NC (https://www.med.unc.edu/bric/ideagroup).
Hi Rest experts! I have a question about the preprocessing steps for the FC map.
With a TR=2s the slice timing correction is really necessary?
Thanks!
Federico
Could someone confirm that AAL01TC to AAL90TC files in the AALTC.mat are
in the following order?
老师:
做双样本t检验的时候,是不是一定要做校正,可是做过FWE或者RDR的校正后,就没有任何显著差异的脑区,怎么办?
大家好:
我看了严老师的视频后,对如何去掉脑外体素仍然不太懂,不知道rest软件能不能解决。希望得到大家的帮助。谢谢!
(希望大家说的详细些)
尊敬的各位老师,我是一名刚接触rest-fMRI的初学者,之前用spm8处理被试时得到以下头动曲线,显然500以后那部分头动超过了标准,这样的被试还能用吗?能否人为的删除掉不合格者部分文件,然后继续处理,这样能得出合格的结果吗?后来用DPARSF处理的时候出现以下错误提示:
老师好,我在使用了DPARSFA2.2时,选择了degree centrality这个选项,在给出的一些文件中,选择了zDegreeCentrality_PositiveWeightedSumBrainMap这一类文件做了吸烟者和控制组的双样本t检验。听了老师的在网上的讲座,有些问题希望确定一下。
1、R值的阈限是从0.25开始取,一直取到1之后,做的这些结果的平均吗?
2、加权值不仅是考虑到了每个voxel和全脑其他voxel相关显著数目,而且考虑了值的大小是吗?
3、转化成z值的数据(以z值开头的文件)和平均值的数据(以m开头的文件),选择哪个较好?
大家好:
对正常组,抑郁组ReHo进行双样本T检验得到的差异图。我有几个问题想问问大家
(1)在此图中有一些体素出现在了脑外区域,这是为什么呢,是我在处理数据是的问题么?
(2)有什么方法可以剔除这些体素么?
谢谢大家!
I processed a batch of subjects through the New Segment + DARTEL step and experienced no obvious difficulties. But when I tried to rest a subset of those subjects through the rest of the pipeline, I got the following error:
