Here, we’ll see how to track redun workflow runs with LaminDB.


This use case is based on github.com/ricomnl/bioinformatics-pipeline-tutorial.

Register the workflow#

import lamindb as ln
import json

Register the workflow in the Transform registry:

How to amend a redun workflow.py to register input & output files in LaminDB?

To query input files via LaminDB, we added the following lines:

# register input files in lamindb
# query & track this pipeline
transform = ln.Transform.filter(name="lamin-redun-fasta", version="0.1.0").one()
# query input files
input_filepaths = [
    file.stage() for file in ln.Artifact.filter(key__startswith="fasta/")

To register the output file via LaminDB, we added the following line to the last task:


Run redun#

Let’s see what the input files are:

!ls ./fasta
KLF4.fasta  MYC.fasta  PO5F1.fasta  SOX2.fasta

And call the workflow:

!redun run workflow.py main --input-dir ./fasta --tag run=test-run  1> redun_stdout.txt 2>redun_stderr.txt

Inspect the output:

!cat redun_stdout.txt
💡 lamindb instance: testuser1/redun-lamin-fasta
❗ this creates one artifact per file in the directory - you might simply call ln.Artifact(dir) to get one artifact for the entire directory

artifact = ln.Artifact.filter(key="data/results.tgz").one()  # query by name

Register the redun execution id#

If we want to be able to query LaminDB for redun execution ID, this here is a way to get it:

# export the run information from redun
!redun log --exec --exec-tag run=test-run --format json --no-pager > redun_exec.json
# load the redun execution id from the JSON and store it in the LaminDB run record
redun_exec = json.load(open("redun_exec.json"))
artifact.run.reference = redun_exec["id"]
artifact.run.reference_type = "redun_id"
