Thu, 09/19/2013 - 03:23Chen0075Hi, Yan, Can I use REST to obtain regional gray matter volume (e.g. PCC) with a binary mask. I mean real volume rather than mean "volume" in that area. If I need the codes;could you tell me what is the code in REST. Great thanks!10530 reads

Fri, 09/13/2013 - 23:37taolei329大家好，我的课题是老年性痴呆的功能磁共振研究，最近向导师汇报科研进度时，他问我能否把弥散张量的FA图与静息态图像进行融合，这样就可以对两者进行综合相关分析，我也查了一些文献，确实有一些研究者将两种图像进行了融合，于是我自己尝试了一下。 我用的磁共振是SIEMENS Trio 3.0T，文献上用的是GE或者飞利浦的磁共振，然后说将FA图进行空间标准化后，利用MRIcro软件将其与fMRI融合，我的理解是把FA序列得DICOM图像进行NORMALIZE后得到的文件叠加在MRIcro的fMRI图像上，...7798 reads

Fri, 09/13/2013 - 15:22shengk请问一下，当三组间进行完ANOVA的分析后，发现有差异，再进行三组间的两两间的比较。在这个过程中怎么进行多重比较校正呢？应该是先针对ANOVA的结果校正一次，然后在两两比较时再次进行？用REST软件里面的Alphasim可以完成吗？谢谢~！13480 reads

Wed, 09/11/2013 - 08:58Authenty各位老师和Resters， 教师节刚过，首先补送一句教师节快乐！ 我在用VBM分析80位正常人的T1结构数据，由于已经有大量研究作为理论基础，我希望有选择性地提取出那些参与疼痛表征和调控的主要脑区（S1，S2，PFC，ACC，Insula和Thalamus）的灰质和白质volume，因此需要做一个只包含这些脑区的mask，但是在制作这个mask时，我遇到一些困难： 问题1. 首先，我尝试在BA模板中找到与以上6个脑区对应的mask，但是，发现BA模板中很难界定thalamus和insular，于是，...6732 reads
