SLICE VIEWER

Submitted by sisina on Sat, 02/28/2009 - 00:25

Hi All,

I am a new REST toolkit user,

I would like to know which images I should use in the slice viewers windows (UNDERLAY-OVERLAY), in order to highlight activation.

I have uploaded structural and ReHo map but matlab gives and illegal image error message.

Best Regards

用SPM5的PairedTTest处理数据时，选择刺激组和对照组数据的先后顺序对结果有影响么？

我分别试了对调它们的顺序，然后contrast都是1 -1，发现结果一模一样，T值的正负也是一样。

如果说数据选择的先后顺序没有影响，那应该如何来解释结果呢？比如说刺激数据在前，对照数据在后，contrast是1 -1，那T值是正值的脑区代表的是刺激>对照，还是刺激<对照？
