Very high t-values

Submitted by njl0930 on
Forums

Dear all,

I'm getting very high t-values from the GLM (screenshot attached). I wondered if this is an issue due to my setup (also attached) or potentially something else? I also can also only export the f-values, the t-values do not seem to export when I save the results.

Any advice would be much appreciated!

Thanks.

How to add atlas in DPABI_VIEW?

Submitted by MMIINNK on

I am trying to locate the position of some brain structures in DPABI_VIEW with the atlas provided.

However, existing atlas can only show rough structures while I want the position of some fine structures.

I tried to find some atlas on the internet whose file format are ".nii", but DPABI_VIEW needs both ".nii" file and ".mat" file to successfully add an atlas.

I wonder how I can succefully add an atlas to DPABI_VIEW and if there is any recommended website for me to easily find suitable atlas and corresponding “.mat" file.

有关标准化的一些问题

Submitted by CrystalLI on

严老师 您好!:

我是一名初学者,目前正在学习应用dpabi对静息态数据进行处理,想请教一些有关normalize 的问题。

在控制面板中我发现normalize的默认参数为[3 3 3],通过检查我自己的.dcom数据发现原始数据是[2 2 2.3]。想请问一下1)在处理这批数据时我需要将默认参数修改为「2 2 2」吗?2)如果我需要修改,那前面的bounding box 需要修改吗?3)我其实自己尝试了将参数修改,但在最后进行统计分析的时候如果需选择61*73*46的模版统计时会报错,但如果选用自制90%的mask就不会报错,想问一下我应用生成的90%的mask有没有问题,为什么在「3 3 3」的时候61*73*46 模版可以进行统计,而「2 2 2」时不行?

关于结构像数据的一些信息的咨询

Submitted by jessica on

管理员,您好

我们最近做了一篇基于结构做分类抑郁症的文章,其中有两条审稿意见需要贵组提供一些帮助,这两条意见如下:

1.审稿人提到没有列出T1图像的参数。审稿人问到这25个站点的参数是一样的吗?如果没有,是否采取了措施将网站的影响降到最低?

2.审稿人还问了用药等情况,但表里面没有服药和首发复发情况,请问能不能把这个信息也共享一下。

非常期待您的回复,如果能得到您的帮助,我们会非常感谢!

The question about the parameters of T1 images and information of medication

Submitted by jessica on

To whom it may concern, 

We submited a research paper about the MDD classification based on structural MRI (T1 image) to Cerebral Cortex, and two of the review comments is:

1. No parameters of T1 images were listed. Are the same across 25 sites? If not, did the author take measures to minimum site’s effects?
