Dear .
I gave a try to the docker version of the great fetal brain segmentation tool you provide. I ran the fetal brain segmentation of 3 stacks using niftymic segmentation command. I should precise I ran the docker with singularity on a high performance computing cluster (slurm interface). When launching the segmentation I obtained the error below:

The .pt file seems to exist (at least when I run the singularity image) but the script serialization.py can not read it.

Do you have any hint ?
Have a good day

in my case previous singularity build, permission of the file is incorrect
