Dear REST experts:
Recently I used the REST correlation analysis, then there were some error messages during the processing (please see the attached file)
Can anybody help me debug this problem? Thank you.

你们好!
不好意思,打扰你们了,我想请教各位一个如何提取各个脑区的体积信息。结构的数据我已经有了,用VBM处理过数据,但我感兴趣的是每个脑区体积的信息,而不是总体灰质或白质的情况,比如我想提取AAL模板中第58个脑区的体积数据
,不知道有没能软件能实现这个功能。
谢谢!!
Hi, I recently download the REST toolbox. I wonder why the ideal Band Pass option is disabled in fALFF gui? I would think one'd want to band pass for this analysis, like in ALFF analysis?
Also, just want to check. For input files entered in ALFF, fALFF, and RoHe gui, I should use preprocessed data (after realign, slice timing, normalize and smooth?)
Thanks very much.
各位老师:
你们好!我想请教一个困扰很久的问题,我在处理数据统计ReHo结果时(其实计算其他方面如任务态的激活区也一样),单样本t检验的结果还好,绝大多数统计增高区峰值点在灰质区,可是一做双样本t检验或者配对t检验,统计增高区就会遍布在白质,脑室脑池内等等,而峰值坐标位于灰质区的很少。我想请教老师,这是什么原因啊?以前听老师讲在做双样本或者配对t检验时,要加入协变量,这个怎么实现啊?谢谢老师!
1.DPARSF_V2.0_110505中BoundingBox Size为 【-90 -26 -72;90 90 108】,SPM中默认为【-78 -112 -50; 78 76 85】,论坛中严老师提到后者的大小过小。
请问,我如何确认什么样的BoundingBox Size比较适合我的数据?
2.BoundingBox Size是以什么为坐标原点的?
3.改变DPARSF_V2.0_110505中BoundingBox的默认值后,后续分析过程出错(回归头动等协变量),如何解决?
