Issue with 2 timepoints and 1 segmentation mask

[Nour-MZ]

Hello,

Im currently working on a dataset that contains 2 scans for the same patient at 2 different time points but with only 1 segmentation mask (difference mask). Therefore, i can't create a proper patientstr.json file since my my data is named as:

imagestr
id1_000.nii.gz
id1_0001.nii.gz
id2_000.nii.gz
id2_0001.nii.gz

where both scans have a single segmentation mask:
labelstr:
id1_0000.nii.gz
id2_0001.nii.gz

Its seems that this isn't supported out of the box, but is there a workaround to make it work?

Thanks

Hi @Nour-MZ,

that is something, which came up a few times already (see here and here). Unfortunately, I still didn't fine the time to properly implement that, therefore I would still refer you to the hacky solution of using a mask containing only the ignore label for images, which don't have a proper label. However, keep in mind that this will not yield the best results.
As the demand for such a solution seems to be quite high, I will try my best to get to that as soon as possible.

Best,
Yannick
