Comparison with different methods with our fmri sc segmentation model

[rohanbanerjee]

This issue is to track the qualitative and quantitative comparisons of different spinal cord segmentation models -- sct_deepseg_sc, sct_propseg, sct_deepseg -task seg_sc_epi and sct_deepseg -task seg_sc_contrast_agnostic.

I am using this script to run the models on the held-out_test data and generate the QCs.
