Split an ImageDatastore with every 'pth' file per label

Hi, the splitEachLabel() for the imageDatastore() when used as

if true
  [imds1,imds2] = splitEachLabel(imds,p)
end

the code above, if p is an integer, the new datastore imds1 contains the first p files from each label and imds2 contains the remaining files from each label. However, I wish to divide my Image Datastore into two data stores the first one with every 'p'th file from each label. I.e., if p=2 every second file of the label should be stored in imds1 and the rest in imds2. How to do this?

There is no built option to do this. You will have to write custom function.splitEachValue method is works on ImageDataStore class. So, you can create a custom function and pass the ImageDataStore object into it and inside the function implementation you can access the IDS object and create new IDSs based on his requirement
