Problem with calcGrains for one specific phase

[Fred - Mtex]

Hi evereyone,

I've got a problem with calcGrains, when I try to calculate the grains of only one phase (mtex 5.1.0)

[grains,ebsd('Iron').grainId]=calcGrains(ebsd('Iron'),angle,5*degree)

This work well at home on Matlab R2018a. But at work, on R2014a, I have this error :

Error using EBSD.calcGrains
Too many output arguments.

Is it a known issue of version of Matlab ?

Thanks a lot

Fred

Hi,

angle in your code should be quoted:

[grains,ebsd('Iron').grainId]=calcGrains(ebsd('Iron'),'angle',5*degree)

If this doesn't solve the issue, I believe that dot indexing was first implemented with Matlab 2014b. Maybe this also might be a problem. After importing the EBSD data can you access the properties with

ebsd.prop

? 

Best,

Filippe

If you try

[grains,grainId]=calcGrains(ebsd('Iron'),angle,5*degree)

do you still get the error?

Hi Ralf,

Trying this, I get another error (Matlab R2014a) :

Error using angle (line 13)
Not enough input arguments.

Hi Fred,
angle is an option, use 'angle' and try again.

Hi Felipe,

ebsd.prop is working well in R2014a

The unquoted 'angle' was just an error posting my message, but in my code it is quoted. So that's not the problem.

I just want to add that

[grains,ebsd.grainId] = calcGrains(ebsd,'angle',10*degree);

works well

Thanks Rudiger !

Works well with :

[grains,grainId]=calcGrains(ebsd('Iron'),'angle',5*degree)

Thanks a lot !!

Best regards

Fred
