Group gray matter density mask

Dear Experts

I would like to genearate a group GM mask by using DPABI's quality control module.

In my understandings, I could generate a GroupMask90Percent.nii based on wAutomask, and then thresholding the mask.

  1. How to create a group specific GM mask by using QC module?

In addition, all images must have the same dimension for statstiscal analysis.

If a group GM mask was generated using SPM Masking toolbox, and then reslicing the mask.

DPASFA做功能连接时的输出文件

严老师,您好!

   我在用DPASFA做功能连接时对输出结果有一些疑惑,想跟您询问一下。

   我选取了14个AAL脑区做成一个MultipleLabel的模板,勾选了Functional Connectivity和Extract ROI time course。

   在输出的结果中,FC_FunImgARCWSF文件夹中的SeedSeries和ROISignals_FunImgARCWSF的值不一样。我的理解是SeedSeries和ROISignals应该都是某个脑区信号的时间序列的平均值,请问我的理解对吗,如果不对,那这两个文件实际上对应的是什么值?另外,FC_FunImgARCWSF文件夹中的ROI1FCMap_sub1.nii文件是某个脑区所有体素的信号均值与全脑的连接强度,还是某个脑区的中心坐标的信号与全脑的连接强度?

   期待您的答疑,十分感谢!

PALM approaches: PT TFCE

Dear Experts

For PT with TFCE, both FDR & Two-tailed were set.

In my understandings, PT were tested at two-tailed P<0.05 with number of permutations being carried out in the analyses. In addition, FDR & FWE were also examined.

Concatenate time-series across runs

Dear experts, 

We performed three separate fMRI runs, during which we applied muscle vibration at 60 Hz and at 20 Hz in blocks of 18s, which were separated by 18s blocks of rest (no vibration). Each block is preceded by a short verbal instruction (3s, 1 scan). By contrasting 60 Hz to 20 Hz vibration, we determine brain activation during proprioceptive processing.

ADHD datasets for 3 dimensional neural network predicting model

Hi
 
My name is Yasuyuki Okubo and I'm building 3 dimensional convolutional neural network predicting model inspired by the paper below.

From this site, I reached R-fMAPs project for the datasets and succussfully downloaded the ADHD datasets for ADHD200 (4. Attention Deficit Hyperactivity Disorder 200 Sample (ADHD-200) ).

Statical analysis - correlation

Dear Chao-Gan,

in SPM, when a correlation analysis in performed, it is necessary to specify the study design (eg. multiple regression).

I am wondering what is the model used in DPABI->Statistical Analysis->Correlation Analysis.

Thank you,

P.
