Two T1w labels for some subjects

[valosekj]

@NathanMolinier and I noticed that some subjects have duplicated T1w labels:

data-multi-subject/derivatives/labels/sub-amu02/anat$ ls -1 *T1w*labels*nii.gz
sub-amu02_T1w_RPI_r_labels-manual.nii.gz
sub-amu02_T1w_labels-disc-manual.nii.gz

T1w_RPI_r_labels-manual.nii.gz

These labels were created in the context of the spine-generic paper on the reoriented and resampled images (see lines here). These files contain only two labels at C3 and C5 mid-vertebral levels (because we used only two labels for the registration to the template), see lines here. These labels are available only for 31 subjects (those where the automatic labeling did not work).

T1w_labels-disc-manual.nii.gz

These labels were created manually by @NathanMolinier using the manual-correction.py script in the original images (i.e., no reorientation and resampling were applied). These files contain disc labels for all visible discs. These labels are available for all the subjects.

@NathanMolinier pointed out that it might be confusing to have two "labels" files.

Potential solutions:

• clarify the difference between the label files in README.md
• suggestion from @NathanMolinier: remove T1w_RPI_r_labels-manual.nii.gz files
