latchbio-整合

使用 Python SDK、CLI、Latch Data 與 Registry、Nextflow、Snakemake、程式化執行及 Latch MCP 來建置、註冊、偵錯與操作生物資訊工作流程。適用於撰寫或部署 Latch 工作流程、設定資源或介面、移動資料、整合 Registry,以及啟動與監控執行作業。

latchbio-整合 是什麼?

此技能專為在 LatchBio 平台上開發、註冊、偵錯及操作生物資訊工作流程而設計。它支援 Python SDK、CLI、Latch Data 與 Registry、Nextflow、Snakemake、程式化執行以及 Latch MCP 等多種方式。技能文件以 **Latch SDK 2.76.8** 為基準,提供建立 Python 工作流程與任務圖、設定資源(CPU、記憶體、儲存、GPU、快取、重試、超時)、操作 Latch Data(LPath、LatchFile、LatchDir)、讀寫 Registry 專案與表格,以及設計表單、啟動計畫、樣本表和結果連結的詳細指引。文件中還包含一個路線表,引導使用者根據任務需求快速找到正確的參考文件(如 workflow-creation.md、data-management.md)。整體開發生命週期建議從相容性檢查開始,經過型別介面定義、資源設定、透過 latch register --staging 和 latch develop 進行鏡像偵錯,最後再正式註冊與監控。此外,文件強調操作安全,例如在啟動付費運算或刪除資料前要求使用者確認,並禁止記錄機密資訊。此技能隸屬於 K-Dense 的 Scientific Agent Skills,使用時應正確引用其論文。

LatchBio 整合

目前基準

此技能針對 Latch SDK 2.76.8(於 2026 年 7 月 10 日發布)。該套件的後設資料支援 Python 3.9–3.12,並聲明相容 Python 3.9+。

當指南內容與 SDK 有出入時,以已安裝的套件及其變更日誌為準。部分 Latch 指南仍保留較舊的 Python 範圍或特定相容性的預發佈版本限制,特別是 Snakemake v2 教學。切勿混用不同管線的指令或匯入,除非已檢查其版本需求。

使用時機

使用此技能以:

  • 建立或維護 Python SDK 工作流程與任務圖
  • 打包並註冊 Python、Nextflow 或 Snakemake 管線
  • 設定任務的 CPU、記憶體、儲存、GPU、快取、重試與超時
  • 透過 LPath、LatchFile、LatchDir 或 CLI 操作 Latch Data
  • 讀取或更新 Latch Registry 專案、表格與記錄
  • 設計工作流程表單、啟動計畫、樣本表、訊息與結果連結
  • 使用 latch register --staging 與 latch develop 暫存並偵錯工作流程映像
  • 透過 Python 或 Latch MCP 啟動與監控工作流程
  • 探索並使用可立即執行的 Latch 工作流程

前往正確的參考文件

僅讀取任務所需的參考文件:

需求參考文件
Python 工作流程、任務、映射、條件、快取references/workflow-creation.md
LPath、舊式檔案類型、Latch URL、資料 CLIreferences/data-management.md
Registry 讀取、交易、樣本表references/registry.md
CPU、記憶體、儲存、GPU、動態資源references/resource-configuration.md
Nextflow 與 Snakemake 打包references/nextflow-snakemake.md
後設資料、表單、啟動計畫、訊息、自動化references/ui-and-automation.md
註冊、開發、執行、監控references/operations-and-debugging.md
可立即使用的工作流程與 latch.verifiedreferences/verified-workflows.md
遠端 MCP 設定與工具工作流程references/latch-mcp.md

在依賴某個符號之前,請針對目標 SDK 版本執行 scripts/inspect_latch_sdk.py。它只會進行本端匯入,不會進行身分驗證或發出網路請求。

安裝與身分驗證

使用可重現的環境:

uv venv --python 3.12
source .venv/bin/activate
uv pip install "latch==2.76.8"

在 Windows 上,使用 WSL 執行文件中記錄的 Linux 工作流程工具。

透過支援的 OAuth 流程進行身分驗證;請勿手動讀取、列印、複製或解析 ~/.latch/token:

latch login
latch workspace

當工作區的數值 ID 已知時,可以非互動方式選擇工作區:

latch workspace --id 12345

latch login 的憑證適用於 SDK 與 CLI。Latch MCP 使用不同的 OAuth 授權,其憑證不可重複用於一般 SDK 存取。

快速路徑

建立並遠端註冊已維護的子流程範本:

latch init covid-wf --template subprocess
latch register --yes --open covid-wf

遠端映像建置為預設值。僅在本地 Docker daemon 可用且是有意進行本地建置時,才使用 --no-remote。

最小化 Python 工作流程

保持工作流程主體宣告式:呼叫任務並回傳它們的 promise。在任務內部執行計算與副作用。

from latch import small_task, workflow


@small_task
def reverse_complement(sequence: str) -> str:
    table = str.maketrans("ACGTacgt", "TGCAtgca")
    return sequence.translate(table)[::-1]


@workflow
def reverse_complement_workflow(sequence: str) -> str:
    """回傳 DNA 序列的反向互補序列。"""
    return reverse_complement(sequence=sequence)

當生成的介面需要自訂標籤、區段、驗證規則、樣本表或文件連結時,請使用 @workflow(metadata)。對於自動任務輸入暫存與輸出上傳,請使用 LatchFile 或 LatchDir;對於指令式遠端路徑操作,請使用 LPath。

建議的開發生命週期

  1. 檢查相容性

    • 確認已安裝的 SDK 與 Python 版本。
    • 識別專案為 Python、Nextflow、舊式 Snakemake flag 路徑,或獨立固定的 Snakemake v2 教學管線。
  2. 定義型別介面

    • 為每個工作流程與任務的輸入和輸出添加型別註解。
    • 保持模組匯入時間無網路呼叫、資料變更與祕密擷取。隔離文件化的例外,例如 workflow_reference,它在裝飾器被評估時解析活躍的工作區。
    • 對結構化參數使用 dataclass 與 enum。
  3. 設定後設資料與資源

    • 使後設資料參數鍵與工作流程簽名相符。
    • 從具名任務裝飾器開始,僅在測量需求證明有其必要時才使用 custom_task。
  4. 在執行映像中驗證

    新的 Nextflow 和 Snakemake 專案在暫存前必須生成其版本相容的 Python 進入點。在 SDK 2.76.8 中,暫存分支不會從 --nf-script 或 --snakefile 生成進入點。

    latch register --staging .
    latch develop .
    

    在變更 Dockerfile 或相依性後,重新執行暫存註冊。在開發容器內所做的編輯不會回同步。

  5. 審慎註冊

    latch register --yes --open .
    

    有用的控制項:

    latch register --workspace-id 12345 .
    latch register --mark-as-release .
    latch register --workflow-module wf.custom_entrypoint .
    

    重複註冊會以狀態碼 2 退出;這與建置失敗不同。

  6. 僅在檢視成本與參數後才啟動

    • 偏好使用 Console 或 Latch MCP 進行互動式操作。
    • 對於 Python 自動化,偏好使用 latch_cli.services.launch.launch_v2。
    • 不要將已棄用的 latch launch CLI 作為新的整合模式。
  7. 監控與驗證

    • 檢查終端狀態、任務日誌、結果連結與科學輸出。
    • 將成功的編排視為必要但非充分的科學驗證。

操作安全

  • 在啟動付費運算(尤其是 GPU 或大型批次任務)前要求確認。
  • 在執行 LPath.rmr、latch rmr、Registry 刪除或覆寫共享目標前要求確認。
  • 絕不記錄祕密、SDK 權杖、已簽署的 URL 或機密值。
  • 僅在任務內部呼叫 get_secret(),回傳值僅用於其預期服務,且絕不回傳作為工作流程輸出。
  • 不要將不可信任的字串傳遞給 shell 指令。偏好使用引數清單搭配 subprocess.run(..., check=True)。
  • 在發布時固定 SDK 與工作流程的相依性。僅在檢視變更日誌並重新執行暫存測試後才進行升級。
  • 將生成的檔案視為生成內容:自訂文件化的擴充檔案,而不是編輯 CLI 會覆寫的輸出。

檢查已安裝的 SDK

從此技能目錄中執行:

uv run --no-project --python 3.12 --with "latch==2.76.8" \
  python scripts/inspect_latch_sdk.py

使用 JSON 輸出進行自動化比較:

uv run --no-project --python 3.12 --with "latch==2.76.8" \
  python scripts/inspect_latch_sdk.py --json

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.
