imagedatastore, Add Folder location

Hi

for the Folder in imagedatastore, afterrandomizeing the images order and labels, the folder value changed from

"C:\Users\R_9_1_GSM_5_original"

to

val=

any way to manually add location again?

the problem accured as follow: as i have 4 imagedatastore and i need to randonly resort the images for all the datastore in the same manner.

for a dataset with two classes (good and bad), when i split data as :

[imdsTrain,imdsValidation] = splitEachLabel(data,0.75)

i will get the images in Files as Good Good Good Good Good Good Good ....948 time then i will get 250 bad bad bad bad bad ...

so i used to change the order and changed the labels manually.

order_train = randperm(numel(imdsTrain.Files))
imdsTrain.Files = imdsTrain_1.Files(order_train);

after these two steps the folder location changed to Val=.

I think shuffle would work fine.

[imdsTrain,imdsValidation] = splitEachLabel(data,0.75);
imdsTrain = shuffle(imdsTrain);

Based on your futher qualification, I think subset would be better.

imdsTrain = subset(imdsTrain_1, order_train);

@Kojiro Saito, that is correct but i need something else that when i use on different datastore like (imdsTrain, imdsTrain_1,imdsTrain_2,imdsTrain_3) give the same ordering.

next image, the labeling doesn't has the same ordering.
