菜鸟求助！MATLAB将岛津数据转为Homer2可识别的数据时碰到了问题

[R0605]

做好了SD文件，将用岛津仪器收集到的近红外原始数据 .txt文件和SD文件用Shimadzu2nirs脚本运行时会报错，能算出部分数据，但是不能转成 .nirs文件。

 报错内容如下：

Index exceeds matrix dimensions.

Error in Shimadzu2nirs (line 79)
   foo(:,i) = d(:,lst);

这是为什么呢？

@太空漫步11 好的非常感谢，我感觉应该是SD文件有点问题，但它又能读出点数据来，我做的是双人脑同步实验，最后SD文件只画了单脑光极板图有用吗？

@R0605 也有可能是您的txt和SD文件不匹配。下面是报错的代码所在的代码块，可以从中看到list(:,1) == SD.MeasList(i,1) 这句在比对list和SD。而list来自于txt文件，那么txt和SD的格式不对的话可能就会出问题。 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % ############# CORRECT CHANNEL LOCATION IN d ACCORDING TO THE SD FILE % AND THE ORIGINAL CHANNEL LOCATIONS OBTAINED FROM TEXT FILE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% list = (C{33,:}); % get the channel information list = regexprep(list,',',' '); % get rid of characters '(' & ')' & ',' list = regexprep(list,'(',''); list = regexprep(list,')',' '); list = str2num(list); % convert to number list = reshape(list,2,size(dc,3))'; wavelength_info = [ones(1,size(list,1)) 2*ones(1,size(list,1)) 3*ones(1,size(list,1))]'; % add wavelength info list = [list;list;list]; list = [list wavelength_info]; for i = 1:size(list,1); lst = find(list(:,1) == SD.MeasList(i,1) & list(:,2) == SD.MeasList(i,2) & list(:,3) == SD.MeasList(i,4)); foo(:,i) = d(:,lst); end d = foo;

@太空漫步11 那我是需要对代码进行修改吗？怎么修改呢？

foo(:,i)=d(:,lst)中foo(:,i)表示foo矩阵第i列。报错是说i越界了，即如果矩阵有4列，i超过了4。
