Per-paper activation maps of the PubMed neuroimaging corpus before the DiFuMo projection: the intermediate output of
data stage 01 (scripts/data/01_coordinate.py, port of docs/02_data/01_coordinate.ipynb).
neuro_vectors_ale.pt (3.5 GB, torch.load): a dict with neuro_vectors, float32 [30826, 28542], and pmid, int64
[30826]. Each row is the ALE kernel map (FWHM 9 mm) of one paper's reported peak coordinates from
neurovlm/neuro_image_papers coordinates.parquet,
in the 28,542-voxel mask of neurovlm/NeuroAutoEncoder
(mask.npz). Rows are in ascending pmid order.
It was written by the notebook on 2025-12-18 with a nimare release that truncates MNI coordinates to voxel indices
(nimare <= 0.15); nimare 0.22 rounds them instead, so a rerun of stage 01 today gives different ALE maps (see the NeuroVLM
repository, scripts/data/README.md). It was written in the same session as the released maps
embedded_text/pubmed_images.pt (the DiFuMo-512 projection of these maps). Its pmids minus the 42 empty rows are
exactly the 30,784 pmids of the released maps. NeuroVLM reads it for supplementary Fig. S2 (DiFuMo vs ALE); it also
lets the projection step of stage 01 be checked on its own.
