    用DPARSF3.1 预处理任务fMRI的时候,第一步就遇到问题,跑出来的funImg 、T1Img 里面是空的,文件整理按照静息态数据的方式,已经跑成功多次了,多次检查了FunRaw 和T1Raw中的数据,应该没有问题:
    ??? Index exceeds matrix dimensions.

     I am using REST-GCA to find granger causality in a network of 264 nodes. Resting-state fMRI time series have 133 time points. However, I encountered the following error:
    Exception occured:
    Index exceeds matrix dimensions.
    When I reduced the number of regions (264 nodes), the error was disappeared.

     老师您好,

    下图是组A单样本t检验的结果(p<.001 FDR校正)

    下图是组B单样本t检验的结果(p<.001 FDR校正)

    同样阈值下,图中组B明显比组A的功能连接更多,但是双样本t检验(组A-组B)的结果(p<.05 未校正)

    Hi,
    I am using DPARSFA to analyze resting state data but I have a problem:
    in the DPARSFA package the function "gmdmp.m" is not present in the subfolder "Subfunctions" and this generates an error when I check the 'Voxel-specific Head Motion' box.

    老师,您好!
    我想问一下,由于我的fmri数据太大,转换成hdr/img文件共2400个,所以没有办法一次做detrend和filter,总是out of memory,而且试了很多次大概一次240个对象(120个hdr和120个img)比较合适,那么如果我把它们分开放在几个文件中分别做detrend和filter可以吗?这么多的time points,我应该去除前多少个比较好呢,或者用多少个比较好呢?
    我现在用的是spm8,数据是转成3D的nifti还是4D的好呢?
