NeuroKit2

使用 NeuroKit2 构建或审核生理时间序列预处理、事件/区间分析、多模态对齐、变异性和复杂性的可重复研究流程。当代码导入 neurokit2 或需要其当前 API、模式和方法感知验证时触发,不用于诊断或设备验证。

NeuroKit2 是什么?

此技能专为使用 NeuroKit2 进行方法感知、可重复的生物信号研究而设计。它基于 2026-07-23 检查的稳定 PyPI 版本 0.2.13,提供了精确的运行时签名、合成输出模式和防止常见错误(如从列名推断单位或假设通用列列表)的严格数据契约。该技能定义了清晰的边界:NeuroKit2 的输出绝不能用于诊断、医疗设备验证或声明生理构造的有效性。它提供了一个完整的可重复工作流程,包括特定序列的预处理步骤(检查、清理、峰值检测、派生物)、会话验证脚本和固定依赖项的安装命令。当前模式涵盖了 ECG 与心率变异性分析(包含持续时间感知的 HRV 指标和峰值修正)、EDA 与显式分解方法、事件和 epoch 处理(包含样本精确窗口规划)、以及 RSA 和多模态处理。复杂性函数被记录为返回包含元数据的元组,强调了长度、平稳性和参数敏感性。该技能还包含一系列 CLI 辅助脚本,用于生成合成数据、检查信号、规划 epoch 和验证多模态清单,所有这些脚本都注重安全性和确定性输出。支持平台包括 NeuroKit2 Python 库,且该技能作为 Scientific Agent Skills 项目的一部分被引用。

NeuroKit2 是做什么的?

范围与证据截止日期

使用此技能进行方法感知的、可重复的生物信号研究。快照于 2026-07-23 检查,对照:

  • 稳定版 PyPI 0.2.13,发布于 2026-03-02;
  • Python 元数据(>=3.10;分类器 3.10–3.14)和 wheel 依赖;
  • GitHub 发布说明/标签,NEWS.rst,标签 v0.2.13 的源代码;
  • 官方 API 页面/示例(现场站点标识自身为 0.2.13.dev214);以及
  • 固定的 0.2.13 运行时签名和合成输出模式。

实时文档可能领先于稳定 wheel。对于可重复的工作,应优先使用固定的运行时,并在查阅开发文档时同时注明两个版本。

边界

NeuroKit2 是一个研究和教育工具箱。不要将其输出呈现为:

  • 诊断、治疗建议、患者监测决策或警报;
  • 医疗器械的验证、认证或监管证据;或
  • 生理构造在新传感器、协议、环境、人群或疾病组中有效测量的证明。

验证采集硬件、电极/光极放置、单位、采样率和时钟精度、预处理、检测器/分解方法、人群、任务和预期研究的结果。保留原始数据和可审计的排除日志。仅使用去识别的本地文件;不要在提示、日志、示例或捆绑的测试固件中放置 PHI。

可重复安装

uv pip install "neurokit2==0.2.13"

对于可选功能,创建一个 uv 项目,仅添加审核过的确切版本所需的包,并在 uv sync --locked 之前提交/审核生成的 uv.lock。NeuroKit2 暴露了一个上游 full extra,但此技能有意不在自动化工作流中安装那个浮动的传递集。可选功能可能需要 MNE、cvxopt、Plotly、PyEMD、pyRQA、Pillow、OpenCV 或文件读取器。记录解析后的环境与分析结果。将任何 MNE 数据/模板下载作为明确、带校验和的研究输入提供。不要为可重复的研究安装移动的开发分支。

必需的数据契约

在处理之前,记录:

  1. 信号标识和传感器/通道配置;
  2. 以 Hz 为单位的原生采样率和物理单位(或显式 arbitrary_unit);
  3. 时钟、时间戳起点、漂移校正和同步证据;
  4. 极性/方向和采集端滤波器/增益;
  5. 缺失样本、不连续性、饱和、平线、运动伪影和注释;
  6. 事件起始点是基于零的样本索引还是秒;
  7. 计划的预处理顺序、方法、参数、排除项和输出;以及
  8. 参与者和组别分组,以防止后续统计中的泄漏。

绝不要从列名推断单位。不要静默地将样本视为毫秒、伏特、微西门子或任意单位。

核心工作流

1. 转换前检查

python skills/neurokit2/scripts/inspect_signal.py \
  --input recording.csv --root . --deidentified \
  --columns ECG,RSP,EDA --time-column time_s \
  --units ECG=mV,RSP=a.u.,EDA=uS

检查器是有界的,不输出行值或路径。在滤波之前解决非单调时间、重复样本、间隙、非有限值、平坦段和采样率不一致问题。

2. 保留预处理顺序

使用此默认推理顺序,根据采集和引用的方法进行调整:

  1. 保留不可变的原始信号和注释;
  2. 验证时间基准、单位、极性、裁剪、间隙和伪影;
  3. 在长间隙处分段;仅在声明的策略下插值短间隙;
  4. 以原生采样率应用模态特定的清理;
  5. 检测峰值/起始点或分解分量;
  6. 检查质量输出和原始叠加图;
  7. 仅使用记录的类别和敏感性检查来校正峰值;
  8. 导出速率/特征;
  9. 在声明的公共时间网格上对齐连续模态;以及
  10. 将事件索引映射到该网格,进行分段、基线化和分析。

不要将二进制标记或峰值索引数组作为普通的连续信号进行重采样。将其时间戳映射到目标网格。滤波和插值可能会产生边缘伪影和虚假精度;保留填充、缺失和拒绝区域的掩码。

3. 将模式视为运行时观测

返回的列取决于 NeuroKit2 版本、函数、方法、信号可用性和分析模式。永远不要声称某个列列表是通用的。

signals, info = nk.ecg_process(ecg, sampling_rate=250)
observed_schema = {
    "columns": list(signals.columns),
    "info_keys": sorted(info),
}

将观测到的模式与包版本、方法参数、采样率和质量/排除摘要一起持久化。参考文件列出了针对 0.2.13 验证的默认模式,而不是对每种方法的保证。

当前模式

ECG、校正峰值和持续时间感知的 HRV

在稳定版 0.2.13 中,ecg_process() 执行清理、R 峰检测(correct_artifacts=True)、心率、默认 averageQRS 质量、DWT 描绘和相位。

signals, info = nk.ecg_process(ecg, sampling_rate=250, method="neurokit")
time_hrv = nk.hrv_time(info, sampling_rate=250)

检查 ECG_R_Peaks_Uncorrected 和 ECG_fixpeaks_*;校正后的序列不一定是有效的 NN 序列。对于频域/非线性 HRV,强制执行指标特定的持续时间和搏动计数要求。五分钟是传统的短期参考;ULF 是长时间记录测量,从短记录中解释 VLF 是不安全的。不要将 LF/HF 解释为直接的交感迷走平衡。PPG 脉搏率变异性不能与 ECG HRV 互换。

使用有界管道:

python skills/neurokit2/scripts/ecg_hrv_pipeline.py \
  --synthetic --sampling-rate 250 --duration 300 \
  --domains time,frequency,nonlinear

EDA 与显式分解

稳定默认的 eda_process(method="neurokit") 使用高通张力/相位分解,而非 cvxEDA。选择并显式报告分解方法:

clean = nk.eda_clean(eda, sampling_rate=100, method="neurokit")
components = nk.eda_phasic(clean, sampling_rate=100, method="highpass")
markers, info = nk.eda_peaks(
    components["EDA_Phasic"],
    sampling_rate=100,
    method="neurokit",
    amplitude_min=0.1,
)

对于 neurokit/kim2004,amplitude_min 是相对于检测到的最大响应的;它不是绝对的微西门子阈值。cvxEDA 需要可选的 cvxopt。

python skills/neurokit2/scripts/eda_pipeline.py \
  --synthetic --sampling-rate 100 --duration 60 \
  --phasic-method highpass --peak-method neurokit

事件、Epoch 和基线

events_find() 报告基于零的样本起始点;持续时间/间距参数以样本为单位。epochs_create() 以秒为单位接受 epoch 限制。

events = nk.events_find(trigger, threshold=0.5, duration_min=2)
epochs = nk.epochs_create(
    signals,
    events,
    sampling_rate=100,
    epochs_start=-0.2,
    epochs_end=0.8,
    baseline_correction=False,
)

首先规划样本精确窗口:

python skills/neurokit2/scripts/plan_epochs.py \
  --events 1000,2500,4000 --event-unit samples \
  --sampling-rate 100 --recording-samples 5000 \
  --epoch-start -0.2 --epoch-end 0.8 \
  --baseline-start -0.2 --baseline-end 0

在 0.2.13 中,epoch 切片是末尾排他的,但生成的浮点时间索引包含 epochs_end。内置基线校正从 epoch 起点到 t=0 减去 epoch 均值;对于更窄的预先指定的基线,使用手动校正。边界 epoch 会被填充并可能包含 NaN。在分析前决定丢弃/填充/报错。

RSA 和多模态处理

bio_process() 假设所有输入已经共享一个采样率和对齐。它不进行重采样、同步、估计漂移或创建嵌套模态字典;其 info 输出是扁平的。不等长会按索引连接并可能引入 NaN。仅当存在同步的 ECG 和 RSP 时才会添加 RSA。

在调用之前验证严格的本地清单:

python skills/neurokit2/scripts/validate_multimodal.py \
  --manifest streams.json --root . --deidentified

在独立模态 QC 和对齐之后:

bio_signals, bio_info = nk.bio_process(
    ecg=ecg_aligned,
    rsp=rsp_aligned,
    eda=eda_aligned,
    sampling_rate=common_rate,
)
rsa_summary = nk.hrv_rsa(
    bio_signals,
    bio_signals,
    rpeaks=bio_info,
    sampling_rate=common_rate,
    continuous=False,
)

摘要 RSA 是一个字典;continuous=True 在验证的默认工作流中返回一个包含 RSA_P2T 和 RSA_Gates 的 DataFrame。共同记录呼吸并报告其速率/深度/上下文;RSA 不是一个直接的、无上下文的迷走神经张力测量。

复杂性返回值加元数据

在 0.2.13 中,大多数复杂性函数返回 (value, info)。便捷函数也返回两个对象:

features, details = nk.complexity(signal)  # default which="makowski2022"
sampen, sampen_info = nk.entropy_sample(signal)
dfa, dfa_info = nk.fractal_dfa(signal)

默认的便捷选择不是“所有度量”。复杂性估计对长度、平稳性、归一化、延迟、维度、容差、尺度和实现敏感。预先定义它们并运行敏感性/替代分析。

捆绑的命令行辅助工具

所有辅助工具拒绝 URL、路径遍历和符号链接;限制字节数/行数/通道数;除非使用 --force 否则拒绝覆盖;使用惰性科学导入以便 --help 无需 NeuroKit2 即可工作;从不使用 pickle;并生成确定性的 JSON/CSV。真实数据命令需要 --deidentified。

辅助工具用途
scripts/generate_synthetic.py无依赖的确定性 CSV 测试固件
scripts/inspect_signal.py有界的 CSV/时间/间隙/平线检查
scripts/ecg_hrv_pipeline.py固定的 ECG、质量、峰值校正、HRV 工作流
scripts/eda_pipeline.py显式清理、分解、SCR 工作流
scripts/plan_epochs.py样本精确事件、边界、基线规划器
scripts/validate_multimodal.py严格的单位/速率/时钟/对齐模式验证器

生成测试固件而不暴露参与者数据:

python skills/neurokit2/scripts/generate_synthetic.py \
  --output synthetic.csv --root . --duration 30 \
  --sampling-rate 250 --seed 42

安全说明

没有示例或辅助工具使用 Python eval() 或 exec()。诸如 eeg_*、events_* 和 *_eventrelated() 等 NeuroKit2 名称是普通的库调用。如果静态扫描器基于子字符串报告 eval/exec 模式,请检查确切的行,并仅在对不存在动态执行进行确认后,将其记录为扫描器误报。

Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
