matlab - mzcdf2peaks 不接受由 mzcdfread 在 Matlab r2020a 中创建的给定数据

Question

所以我有以下代码和错误：

>> data = mzcdfread('sample1.cdf');

>> mzcdf2peaks(data)
Error using mzcdf2peaks (line 27)
Input structure MZCDFSTRUCT must be created by MZCDFREAD. 

这是一个简单的 .cdf 文件。我希望最终输出为：

但正如您所见，mzcdf2peaks功能对我不起作用并导致此错误：

Error using mzcdf2peaks (line 27)
Input structure MZCDFSTRUCT must be created by MZCDFREAD.

我正在关注这个示例，他们使用以下命令：

mzcdf_struct = mzcdfread('results.cdf');
[peaks,time] = mzcdf2peaks(mzcdf_struct)
figure
hold on

for i = 1:numel(peaks)
    t = repmat(time(i),size(peaks{i},1),1);
    plot3(t,peaks{i}(:,1),peaks{i}(:,2),'color',colors(i,:))
end

view(70,60)
xlabel('Time')
ylabel(mzcdf_struct.mass_axis_label)
zlabel(mzcdf_struct.intensity_axis_label)

当我sample1.cdf在 Unichrom 中打开文件时，它可以工作。

您可以在此处访问 cdf 文件：https ://files.fm/u/j7yjb23c

所以我的问题是如何让 Matlabmzcdf2peaks函数在这个数据集上工作？有没有其他方法可以实现所需的输出？
