I can't run the example "3-D Brain Tumor Segmentation Using Deep Learning"

I can't run the example "3-D Brain Tumor Segmentation Using Deep Learning" in my matlab (R2018b). For instance, there is a sentence in this example, that is, "To train the 3-D U-Net network more efficiently, preprocess the MRI data using the helper function preprocessBraTSdataset. This function is attached to the example as a supporting file.", I have installed these 3 toolboxes:

• Computer Vision Toolbox
• Deep Learning Toolbox
• Image Processing Toolbox

but I still can't use the function mentioned above, preprocessBraTSdataset().

So, I need help. Thanks a lot!

I do not believe this example is available in R2018b. I obtained the same error message in R2018b:

>> openExample('deeplearning_shared/Segment3DBrainTumorUsingDeepLearningExample')

Error using findExample (line 35)

Example "Segment3DBrainTumorUsingDeepLearningExample" not found in "C:\Program Files\MATLAB\R2018b\examples\deeplearning_shared\examples.xml".

Error in openExample (line 24)

metadata = findExample(id);

Are you able to upgrade to R2019a?

Thank you very much! It's the reason that this example is not available in R2018b, I get it. Thanks a lot for your help!

Run the following at the command line:

openExample('deeplearning_shared/Segment3DBrainTumorUsingDeepLearningExample')

Did the function preprocessBraTSdataset appear in your folder?

[Yaoting Yue]

When I run: openExampl('deeplearning_shared/Segment3DBrainTumorUsingDeepLearningExample') at my local command line, it shows erro like following:

>> openExample('deeplearning_shared/Segment3DBrainTumorUsingDeepLearningExample')

erro using findExample (line 35)

in "E:\MATLAB\examples\deeplearning_shared\examples.xml" can't find "Segment3DBrainTumorUsingDeepLearningExample"。

erro openExample (line 24)

metadata = findExample(id);
