  • rest做t检验是z值还是t值
    Sun, 07/14/2013 - 21:41fish
    各位老师：       我在用GIFT软件时，已经把数据转化成z值了，然后我再用rest分别做单样本t检验和双样本t检验，我想问这个时候report报出来的结果应该是t值还是z值呢？谢谢

    Dear DPARSF users, I was wondering if DPARSF is converting the fmri signals from arbitary scanner uints into percentage signal change during the processing step. I will appreciate it if you can let me know. Thanks in advance !! YY

  • 6 motion regressors output
    Fri, 07/12/2013 - 19:30Helen Sawaya
     Dear experts, I am running only motion regression in DPARSFA and looking at the output it appears that the image is demeaned. Does it not output the functional image with the mean added back in order to use it for further processing? Thank you Helen

  • VBM DPARSF
    Wed, 07/10/2013 - 00:26Chen0075
    严老师，您好，请问： 在做VBM的modulation时候我们经常这样选择： 单击Modulated normalized选择“affine+non-linear only”。这里的affine+non-linear only是什么意义，是说T1像经过affine和non-linear两次normalization，然后得到一幅MNI的图像？ 在DPARSFA的VBM里面是如何选择normalization和modulation过程的。 谢谢！
