ORtools - 2.3.0 Example07 issue with computeVariantGrains

[tirdadnn]

Hello,

I had a problem with executing the code in the example 07 :

[newGrains,newEBSD] = computeVariantGrains(job);

I executed all the code sections before this line successfully. The error is as follws:

Unable to perform assignment because the left and right sides have a different number of elements.

Error in [indexing] (Line 127)
dp.prop.(fn{i}) = subsasgn(dp.prop.(fn{i}),s(1),value.prop.(fn{i}));
Error in [indexing] (Line 72)
ebsd = subsasgn@dynProp(ebsd,s(1),b);
Error in computeVariantGrains.m', 87))
newEBSD(idx) = remainingEBSD(idx);

I used the same EBSD data in example 07. But I also executed it for my own EBSD data. Again I had issue with executing this part of the code.

thanks in advance for you assistance.

Hi @tirdadnn

I was unable to replicate your issue.
I ran ORTools_example07 exactly as-is without any error whatsoever.

I believe your issue is due to differences between ORTools and the latest version of MTEX released in 2025.
We are working on a new version of ORTools (along with new tools too!) that is completely compatible with the latest MTEX version - but its release is still quite a few months away.

So the quick workaround for now is to use the latest developer version of ORTools along with MTEX v 5.11.2.

Have a good weekend.
