Hello,
I encounter the same error unfortunately, if you have any ideas I'd be grateful to learn how to overcome this issue.
max=20803.0 for ... is greater than min=20468.0

I might be speaking nonesense as I did not dig into the code, but could the issue be related to this condition from the EDDGridFromFiles.java ?

for (int f = 1; f < nFiles; f++) { //1 since looking backward
    //min max overlap?
    if (ftMax.get(f - 1) > ftMin.get(f)) 
        throw new RuntimeException("Outer axis overlap between files.\n" +
            "max=" + ftMax.get(f-1) + " for " + dirList.get(ftDirIndex.get(f-1)) + ftFileList.get(f-1) + "\n" +
            "is greater than\n" +
            "min=" + ftMin.get(f)   + " for " + dirList.get(ftDirIndex.get(f  )) + ftFileList.get(f  ) + "\n");
}

if max > min throw an error ??!

This part of the code is around 8 years old so there is few chances but it looks a bit odd from my point of view 😆

Have a good day !

I do think that is the section of the code throwing the error, however, the cause of the error is usually due to something wrong in the datasets.xml file. The min+max are typically set there and then compared to the actual values in the chunk of code you have linked.
