如何将原始T1上勾画的ROI配准到预处理好的功能像上

Submitted by lihong on Thu, 01/08/2015 - 12:22

 老师你好，因为需要进行海马的体积分析，我在原始t1图像上勾画海马作为roi，但是我不知道如何将原始图上的roi和预处理好的图像进行配准。自己尝试过用spm的normalise，但是配准结果不好，与预处理的功能图配准不到一起。所以恳切想知道这种情况下我如何进行配准，具体步骤忘请教。谢谢！

MATLAB:nomem error while detrending

Submitted by ma.shalchy on Thu, 01/08/2015 - 12:04

Dear experts

As I want to detrend my fmri images (1200 volumes per subject) matlab runs out of memory. I tried to Turn on the 3GB swithch but I faced a blue screen error afterwards. Detrending option works well on up to 400 volumes. How could I tackle this problem?
I highly appreciate your help.

Best,
mahsa
