xjview出错

我在用xjview的时候，点击volume，总是出现如下错误：

??? Error using ==> spm_P
Too many output arguments.

Error in ==> xjview>spm_list at 6975
[P Pn Em En EN] = spm_P(1,k,u,df,STAT,R,n,S);

Error in ==> xjview>CallBack_volumePush at 5357
spm_list('List',xSPM,handles.hReg);
 
??? Error while evaluating uicontrol Callback


请问怎么处理？
