Concatenate time-series across runs

Submitted by NinaGoossens on Fri, 06/08/2018 - 07:12

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

Submitted by Yasu on Thu, 05/31/2018 - 11:29
Hi
 
My name is Yasuyuki Okubo and I'm building 3 dimensional convolutional neural network predicting model inspired by the paper below.
 
https://ieeexplore.ieee.org/document/8067637/all-figures
 
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

Submitted by Patrizia on Tue, 05/29/2018 - 09:40

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.

seed based FC

Submitted by whtuye on Fri, 05/25/2018 - 05:30

各位好：

      运用DPABI 处理静息态fMRI 数据，得到了ReHo 图，双样本t检验得出两组差异脑区（岛叶），按照文献的做法，以差异脑区（岛叶）为种子点，做seed-based Functional Connectivity (FC),

DPABI一直报错

    我自己的做法如下；

     1.将差异脑区（岛叶）在DPABI VIEW 界面存为MASK

    2 进入DPARSFA界面 ，选择"Functional connectivity" 和“extract ROI time course”   弹出ROI tempalte 对话框，选择 Define other ROI, 弹出ROI list 对话框， 选择+Mask 选择  岛叶 mask.nii 文件

   但一直报错。

One more thing for protecting The R-fMRI Network (RFMRI.ORG): for users who registered in the last 5 months (if you found you can not log in), must re-register at rfmri.org.
