Ask about setting the data of task 3 of the Learn2Reg2020

Hi organizers!

I saw in the Task3 of the Learn2Reg2020 at the Training/Validation have the "pairs_val.csv" file. How do we understand this file?
That file: fixed moving
1 4
1 7
.......
It means, we must to combine the img0001.nii.gz and img0004.nii.gz into the same foder ;img0001.nii.gz and img0007.nii.gz..... into the same other folder to train step, right?
Thank you organizers

Hi ,

the pairs_val.csv indicates which combination are required for the validation evaluation on grand-challenge.

You train your network with all pair that are not included in the pairs_val. You can use all possible combinations during training.

To evaluate your approch, you register the pairs given in the pairs_val.csv and upload the displacement field to grand challenge (see https://learn2reg.grand-challenge.org/Submission/)

Best,
Alessa

Thank you organizers.

Thank you for your last respone.
Allows me ask more. I understood how to combine images in the "img " folder of "Training "folder
And in this "Training "folder, I saw also have the "label " folder more ( label0001.nii.gz, ...)

Question: What for is the label folder in the Image Registration task?
It means, we also will combine the image together follow the "pairs_val.csv" when do train step, right? Please explain to I can do this task. Thank you organizers.
