老师，你好！遇到一些问题，请帮忙！
我做的是治疗前后REHO的变化。对治疗前与治疗后的REHO用REST做了配对T检验，得到有差异的脑区共12个。我想做一下这些差异脑区与临床症状的关系：rest-slice viewer-save cluster。保存了12个ROI的MASK。然后用每个病人的REHO图分别与这12个MASK进行相乘(rest Image calculator做)，共相乘了12次，每个ROI一次。每个ROI得到一组output.image.再把每个ROI的output.image与临床症状评分做相关（text文件），用rest correlation analysis做的，结果报错！报错如下：
