Tue, 01/22/2019 - 21:26helloqsh老师好，我得到了被试的时间序列，想转换为功率谱密度曲线，请问具体怎么操作？谢谢！ 我通过matlab这样做不知道对不对： x=dlmread('*timecourse.txt')；%一个被试的时间序列 y=fft(x); %进行傅里叶转换 N=1060; %数据共有1060 timepoints fs=1./0.392; %采样频率计算为：1./TR，我数据的TR为0.392s f=(0:N-1)*fs/N; %计算数据的频域区间f mag=abs(y); %计算数据的频谱幅值mag %%%因为从f 向量内发现...9232 reads -

Sun, 07/22/2018 - 12:09Sun Yuan老师你好，我之前在做统计分析双样本T检验的时候mask file那里用的是BrainMask_05_61x73x61（因为在一个论坛的回答里面看到），但是在视频里您讲的是要用QC那个模块里生成的group mask，想知道用BrainMask_05_61x73x61可以吗？4793 reads
