Add autoptX/rfMRI IDPs, pipeline success sentinels, and bug fixes New features: Add autoptX tractography IDP extraction (243 IDPs: 27 tracts x 9 metrics) Add rfMRI IDP extraction script and headers Add melodic IC templates (25 and 100 components) Add XTRACT tractography support in dMRI pipeline Write TSV header row before subject loop in IDP extraction Bug fixes: Fix dtifit mask: use nodif_brain_mask (binary) not nodif_brain (intensity) Fix DTI shell selection: use only highest b-value shell Fix GM parcellation: read volume_mm3 column not nvoxels Fix FIRST volumes: output in mm3 using voxel dimensions from fslval Fix FreeSurfer 7 thalamus label renaming (Left/Right-Thalamus-Proper) Fix brc_FS_get_IDPs.py: read values not headers from data_dict Fix dc precision in noise ratio calculation Fix integer comparison in brc_IDP_diff_TBSS.sh Fix b-value float comparison in Pipeline_NODDI_Watson.sh Fix safe variable defaults in Pipeline_NODDI_Watson.sh Fix sed multiple-space collapse pattern in idp_extract_part_1.sh Fix mkdir -p for bedpostxFolder Robustness: Add .DIFF_SUCCESS, .FMRI_SUCCESS, .STRUCT_SUCCESS pipeline sentinels Add result="" initialisation in brc_IDP_all_align_to_T1.sh Remove dead HCP-only code (run_eddy_qunex.sh) Add IDP_list.txt entries for 243 autoptX IDPs (indices 888-1130)
