不同机器扫描出来的MRI数据能合并分析吗吗?还有就是同一种机器不同参数扫描出来的数据可以合并分析吗

How can I get the color bar to show on the montage view ?

Hi Dr Yan,

How can I get the color bar to show on the montage view ? I saw there was a guiding said "you add "+" or "-" flag at the end in "Add Overlay's Colorbar" entry, DPABI_VIEW will use full colormap to display the overlay". But I can't find where the "Add Overlay's Colorbar"  is. Can you show me? Thank you!

Parallel pool error

Hello,

I have been running DPARSF for a while without any issues. However, since yesterday, I have been getting this error when I try to use a parallel pool:

 Warning: File: DPARSFA_run.m Line: 4438 Column: 32

平均灰质模板的构建

各位老师,我按照VBM说明书用dartel tool(creat template)生成了平均灰质模板,Template_0到Template_16 这17个文件,请问哪一个是可用的模板文件?是最后一个?还是根据肉眼精度来判断?肉眼看template_6和template_13比较清晰,最后生成的template_16并不清晰。

我看了一些帖子,别人都是自动生成了6张,选择最后生成的template_6,我是使用的默认设置,不知道为什么会生成17个文件,我只做了creat template是不是已经生成了最终模板,需不需要再运行run existing template那一步?

此外,这个模板文件是否在mni空间?如何标准化到mni空间?

 

如何利用DPABI计算脑区的相对灰质体积?

据说所知,在DPABI里面应用ROI  signal extractor 对mwrp文件进行提取提取的是平均灰质体积,请问如何才能实现计算一个脑区(如海马)的绝对体积或相对体积呢?课题组有师兄是基于AFNI软件用代码实现了脑区内的逐体素相加,DPABI里是否能实现这样的功能呢?

DPABI的Viewer看图问题

老师您好:

         我用dpabi的viewer读图,用underlay打开图片时,MATLAB显示“Cannot access file”,我发现不能读的图是float格式,是因为这个原因么?谢谢老师!期待老师的回复

Inquiry about voxel size change

Dear Dr. Yan,

I have a question about changing voxel size.

I want to get ROI signal by applying Yeo atlas.

I have fMRI data with 3mm voxel size but there are only 1mm and 2mm voxel size Yeo atlas.

So I want to change 3mm voxel size to 2mm in the preprocessing process using DPABI.

Could I simply change voxel size on the DPABI like the image I uploaded?

Could you give me some advice on this problem?

Thank you.
