combraintf SKILL.md skillA

combraintf from cuhk-aim-group/neurodiscovery is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add cuhk-aim-group/neurodiscovery/combraintf@git:20261023.f74c2bd

Pins git:20261023.f74c2bd in mdr.lock. Pin the fingerprint instead.

Use this model doc whenever the user wants to run Com-BrainTF (Community-aware Brain Transformer) for fMRI phenotype prediction. Com-BrainTF uses dense FC matrices with a two-level Transformer (per-community local + global) and DEC pooling. NeuroRuntime auto-derives community partitions from atlas naming conventions (Yeo 7-net for Schaefer, lobe-based for AAL).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Com-BrainTF Model Doc

## Overview
Com-BrainTF (Community-aware Brain Transformer) 是一种针对 fMRI 连接组的两级 Transformer。第一级对每个脑功能社区（如 Yeo 7-network）内的 ROI 独立做 self-attention，并为每个社区维护一个可学习的 CLS token；第二级把所有社区的 CLS + 全部 ROI 节点拼接，再过一个带 DEC 池化的 Transformer，最后展平进 FC head。

- Paper: Bannadabhavi et al., 2023, "Community-Aware Transformer for Autism Prediction in fMRI Connectome"，MICCAI
- Official code: https://github.com/ubc-tea/Com-BrainTF
- NeuroRuntime reimplementation: `models/combraintf/`（去除 hydra/omegaconf 与硬编码 node_clus_map，改为运行时从 atlas 推导）
- Primary input: dense FC 矩阵 [B, N, N]
- Primary output: phenotype prediction + DEC assignment + per-level attention

## NeuroRuntime 实现要点

1. **去除 hydra/omegaconf**：原版用 hydra 配置 + DictConfig，NeuroRuntime 改为纯 Python 构造函数，所有参数显式传入。
2. **动态 community partition**：原版从 `node_clus_map.pickle` 加载 Schaefer-400 的固定社区映射；NeuroRuntime 在 `data_adapter.py::build_community_ids(atlas)` 里根据 ROI 名自动推导：
   - `schaefer_*_7net` → Yeo 7-network（Vis/SomMot/DorsAttn/SalVentAttn/Limbic/Cont/Default）+ Unknown 兜底，共 8 组
   - `aal_*` / `destrieux` / `dk_*` / `harvard_oxford_*` → 7 lobe + Other = 8 组

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/combraintf@sha256:ccfa178e540e6be9

The line at the top of this page pins the label git:20261023.f74c2bd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
