Young Student seeking Assistance in Identifying Error in Preprocessing steps

Hello friends,

I have been working with 206 resting-state images from http://adni.loni.usc.edu/data-samples/access-data/ . I have been going at this for approximately two weeks with relatively little success. Currently it appears I may be successfully completing slice-timing correction, and then having an error during the realignment stage of preprocessing, but honestly I am uncertain where my error resides.

在 REST SLICE VIEWER 里,如何设置CLUSTER SIZE 的值?还有RMM的值?根据什么 原则了来设定,对结果有哪些影响?多谢!

用ICA方法,双样本t检验总是过不了,是不是过程出错了

用ICA方法处理了一批70个数据没有结果,但之前做过功能连接有结果的,没做过ICA,不知道是不是步骤错了,特来问问各位老师们。

1.用gift软件MDL分析只有10个成分,觉得成分太少了就自己定义了20个成分。

2.运行完之后,用gift软件带spm对挑选的成分做病人和正常人单样本t检验。在slice Viewer过FDR校正(0.05),save clusters.然后通过image calculator(i1~=0+i2~=0)做并集mask。
