关于alphasim校正

 想请问一下各位老师:我VBM分析的T检验结果,需要做alphasim校正,是进入rest后,mask选择直接把spm001.mat 这个结果文件当作mask吗? 感觉视频里的mask没有理解透彻,计算起来在matlab中看起来速度很慢。谢谢!

MICA

 请老师指点,运行MICA老是出现以下问题

关于激活图上的正负问题

 老师好:
         我想问下 在做基于种子点的全脑功能连接时,使用SPM做T检验只能做单侧检验,如果在做单样本T检验时,contrast设定为1,然后我在xjview上看结果图设好阈值,点击only+之后的脑区是和种子点功能连接明显高于其他脑区,那only-之后的脑区指的是?使用rest做单样本T检验时做的是双侧检验,这时候的only+和only-之后的脑区是不是分别代表和种子点功能连接显著高于其他闹区以及和种子点功能连接显著低于其他闹区?

MICA

 运行总是出现下面的图片~~张老师能不能帮忙解释下这是为什么??

求助

 各位老师:
       大家好!我想用双样本功能连接的结果与临床症状做相关分析。在提取每个被试的zfc值时,总是报错:Exception occured. ()

DPARSFA Error after normalizing

Hi everyone

I'm preprocessing my data and have encountered an error message. It seems to happen right after the normalizing step and the matlab command window says that normalization is "Done" (however, there is no "W"-folder available in my directory, which is strange). This is what the error message looks like:
