提取协变量时出错

按照COURSE中讲述的方法提取协变量,发现报错,

>> RPCov=load('rp_aSub_001.txt');
>> BCWCov=load('ROI_FCMap_Sub_001.txt')'
>>Cov=[RPCov,BCWCov];
??? Error using ==> horzcat

 same number of rows.

Q&A: Convert r to p

Dear Chao
I have a question regarding you program y_corr2p, that was very useful to me. I would like to know how the P value is calculated. All other algorithms I have been using use the mean(r) and std(r) across all subjects, but your code is independent of the number of subjects, only taking into account the number of time points in the series. I am curious about how it is calculated
best regards
Pablo
