各位好: 今日用DPARSF中的步骤处理task数据(滤波以前所有步骤),数据扫描的时候TR=2. 在处理数据的时候,软件自动报出‘Your TR is 1.8'。同一批数据,还出现了‘Your TR is 1.9'的情况,但是用mricro查看dicom转换为hdr/img的参数,仍然显示TR=2。 请问这是什么情况?

请问rest软件能做重复测量的方差分析吗?

我要做two-way repeated anova,又把每个人的GM map作为了协变量。 rest软件能做把GM整个map作为协变量,但是只能做one way anova,而且rest软件不能做repeated anova。貌似spm软件虽然能做two-way repeated anova,但是不能把整个map放进去作为协变量,只能放进去年龄、性别等这种covariate。 所以我想问下,我要做two-way repeated anova(不是two-way anova), 还要把GM map作为协变量,这个是不是只能自己编程呢?如果自己编程,repeated和不repeated差别在哪,就是写程序的时候注意什么? 如果spm软件能做two-way repeated anova,我没有在full factorial中找到啊?哪里有呢? rest软件可以做吗? 谢谢
