  • i have Brats2017 dataset of Brain MRI images
  • the dataset consists 243 of patients data
  • each patients data consists of 155 slices
  • i am using flair sequence of MRI
  • i have to read every slice of every patient to train and test the Convolution Neural Network
  • because i have every patients data in .nii (NIFTI) format so i dont know how to read this data using ImageDataStore
  • like image data store was used to store 10000 images in digit classification example in matlab
  • kindly help me

Basically you should use some of the pairs in ImageDatastore. To read NIFTI files into ImageDatastore add the name-value pairs below:
ImageDatastore('fileLoc','FileExtensions','.nii', 'ReadFcn',@niftiread)
