Error when loading the patterns

[ysu345]

I tried to run the example data set (followed the steps in the wiki) and got an error after loading the patterns from the GUI (select first image) I am not sure what is wrong, could you help me identify the problem, thanks! Yang

Here is the Error message: **Error using patterns.ImagepatternProvider Error: File: ImagepatternProvider.m Line: 12 Column: 19 Unbalanced or unexpected parenthesis or bracket.

Error in patterns.makePatternProvider (line 30) patterns.ImagepatternProvider(...

Most likely it doesn't like your file names. Can you send an example of the first 3 pattern file names? You can email me directly on dfullwood@byu.edu if you like. Thanks David

I used the example data set. The first 3 pattern file names are: Steel Ferrite-Martensite 40000X w 1x1 Pats_x0y0 Steel Ferrite-Martensite 40000X w 1x1 Pats_x0y10 Steel Ferrite-Martensite 40000X w 1x1 Pats_x0y20

:) I read that too fast. Let me check it... I assume you have the latest version downloaded...

[ysu345]

Yes. I downloaded the .zip code today and also followed the instruction to download the quaternion scripts to the quaternions folder as well. Thanks!

[dtfullwood]

I just pulled the latest version and it worked fine for me. This is line 12 of ImagepatternProvider.m (In folder Code/+patterns/@ImagepatternProvide/) scanFormat(1,:) char {mustBeMember(scanFormat, {'Hexagonal', 'Square',''})} Does your version look the same?

[ysu345]

Yes. it looks identical Mine is scanFormat(1,:) char {mustBeMember(scanFormat, {'Hexagonal', 'Square',''})}

That is really strange... I am using matlab R2016a hope that is fine?

[ysu345]

If I open the ImagepatternProvide.m with matlab editor, the line 12 is marked as an error in the editor, so does the line 21. Line 12: parse error at '(': usage might be invalid MATLAB syntax. Does your editor show the two lines as error, If not I guess there might be something wrong with my MATLAB...

[dtfullwood]

No, there is no error on mine. if you replace the line with the one I sent, does it still give the error? Is it possible that the unzipping process interpreted the characters wrongly? Maybe try a different unzip tool?

[ysu345]

I copied your line 12, and still got the same error. I also tried it on my laptop with matlab2015a, got the same error too. (it is a MacBook so I guess it is not the unzipping process?) I am currently upgrading matlab to 2021a on my office desktop, hopefully it can solve the problem... Btw, could you let me know what version of matlab you were using, thanks!

[dtfullwood]

I have 2019b on this macbook; I think I have 2021 on my other macbook, which also runs fine. Good luck!

Using 2021a matlab, I got no error and works, thanks for your help!

Super! Thanks for letting me know. That is useful information for other people. David
