请教一个关于重采样的问题

Submitted by duxue on Wed, 01/09/2013 - 10:22

 请问当我们想用Rest软件进行重采样的时候，这个软件默认的精度是多少啊？（1*1*1还是3*3*3啊？）在进行重采样的时候，有没有一个原则是只能从精度高的往低的重采样，不能把低的往高地采啊？我们现在想将VBM结果进行Alphasim矫正，当用slice viewer打开我们的结果时会出来一个警告提示我们进行重采样，而我们的结构数据在扫描时是1*1*1，当进行预处理进行配准时变成了1.5*1.5*1.5,所以最后的结果应该是1.5*1.5*1.5的，这样的话我们重采样需要采成多少呢？谢谢老师~~~

Question on setting parameters

Submitted by farras on Wed, 01/09/2013 - 01:10

In the following lines, what does SliceOrder refer to? is it the order of slices from the first slice to the total number of slices? And what is the role of ReferenceSlice?

AutoDataProcessParameter.SliceTiming.SliceOrder=[1:2:239,2:2:240]; % REVISIT.... was [1:2:25,1:2:24]
AutoDataProcessParameter.SliceTiming.ReferenceSlice=25;

With thanks,
