Re: 计算头动的translation和rotation
您好,你的问题能再明确一下吗?

Re: 计算头动的translation和rotation
不好意思,我说的有点乱.有人在spm中计算头动最大值用的是b=load('rp_name.txt');c=max(abs(b));c(4:6)=c(4:6)*180/pi这样一个简单的小公式。在dparsf中会自动见到分类好的头动数据,见fig1。我想问fig2(有关头动的均值和标准差的计算)是否有像类似spm的计算公式,或者其他更简单的?谢谢各位老师

Re: 计算头动的translation和rotation
把max改成mean。
不过,现在报告这已经不流行了。
再起流行报告FD, 尤其是FD jenkinson,可参考:

FD Power或FD Jenkinson,DPARSF都会自动生成。FSL也新出了一个函数,见:http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FSLMotionOutliers
