  • 请问大家如何将fmri图像进行左右翻转?
    Fri, 03/11/2022 - 11:58dandan94
    病变分别位于左侧和右侧半球,希望能将病变翻转弄到一侧,研究对侧的情况,烦请百忙之中答疑,不胜感激!

  • 如何通过dpabi的NBS方法对一组被试的功能连接的连边进行年龄效应分析(不是组间比较,而是进行连续变量分析)
    Wed, 07/21/2021 - 02:49helloqsh
    老师们好: 我有一组被试的功能连接矩阵,我想通过NBS分析哪些连边随着发育增强,哪些减弱,同时把性别和头动作为协变量。 我没有对被试进行分组比较,而是想观察哪些边随着年龄的增长有显著的变化。 那么: (1)在dpabi的Statistical Analysis界面的第一个下拉框里面应该选哪个呢? (2)在Text Covariates里是放入age, sex, mFD三个协变量,还是只放入sex和mFD两个协变量呢? (3)最后在哪个生成的文件里给出age的效应呢? 谢谢老师们! 祝生活愉快~

  • 网上共享数据给出的fMRI数据和atlas的维度不同怎么办
    Tue, 01/05/2021 - 00:51ErickZhou
    下载ABIDE提供的数据,发现fMRI和提供的atlas的voxel size都是3mm*3mm*3mm大小,但是两者的维度分别是: fMRI data 维度 (T is the number of time points).; Harvard-Oxford (HO) atlas 维度. 我尝试去除HO atlas两端的数据,使其维度变成,而后先获取voxel time series,再对各个ROI内的voxel time series取平均,但是得到的ROI time...

  • 使用REST1.8运行ROIwise静息态功能连接,生成的zFC文件中没有相关系数,如图
    Tue, 12/01/2020 - 18:03WJM
    使用REST1.8设置好两个球形ROI之后(FC中的ROIwise选项),添加预处理过的静息态数据,勾选detrend和filter,生成的zFCMap(txt文件)没有生成相关被试两个ROI之间的相关系数,如截图。而且ROI_FCMap(txt文件)也没有按照时间序列生成两列ROI信号值。在运行过程中都没有报错。

  • 请问Harvard-Oxford atlas下的110个Nodes能否归类到几个大网络(resting state networks)
    Mon, 09/07/2020 - 09:26ErickZhou
    请教各位一个问题。 我看到一些文章,都会把Nodes划分到不同网络,比如看到有的文章说到we utilized data from Smith et al.’s study to assign 264 nodes into 10 functional networks corresponding to the primary resting state networks (RSNs) [40]. [40] S. M. Smith, K. L. Miller, G. Salimi-Khorshidi, M....
