Redun 
¶
Here, we’ll see how to track redun workflows with lamindb.
Note
This guide is based on github.com/ricomnl/bioinformatics-pipeline-tutorial.
Amend the workflow¶
Here is how to instrument a redun workflow for tracking with lamindb:
Add
ln.track()to themain()task (see on GitHub)Register desired output files or folders by creating artifacts for them (see on GitHub):
ln.Artifact(output_path, key="data/results.tar.gz").save()
Add a
finish()task that callsln.finish()(see on GitHub)Optionally cache/stage input files (see on GitHub)
Why not use @ln.flow() for main()?
Because main() in redun is typically a scheduler/executor task rather than a task that performs the actual computation. ln.flow() would then just track the execution time of scheduling, and not an actual compute run.
If one wanted to use @ln.flow() it’s advisable to wrap the scheduling main() task:
@ln.flow()
def run_pipeline(...):
scheduler = Scheduler()
result = scheduler.run(main(...)) # run the main task
ln.Artifact(result.path, key="data/results.tgz").save()
return result
Run redun¶
Let’s see what the input files are:
!ls ./fasta
Show code cell output
KLF4.fasta MYC.fasta PO5F1.fasta SOX2.fasta
Create a lamindb test instance:
# pip install lamindb redun git+http://github.com/laminlabs/redun-lamin-fasta
!lamin init --storage ./test-redun-lamin
Show code cell output
→ initialized lamindb: testuser1/test-redun-lamin
Register each input file individually as an artifact:
import lamindb as ln
import json
ln.Artifact.from_dir("./fasta").save()
Show code cell output
→ connected lamindb: testuser1/test-redun-lamin
! folder is outside existing storage location, will copy files from ./fasta to /home/runner/work/redun-lamin/redun-lamin/docs/test-redun-lamin/fasta

Run the redun workflow:
!redun run workflow.py main --input-dir ./fasta --tag run=test-run 1> run_logs.txt 2>run_logs.txt
Inspect the logs:
!cat run_logs.txt

Map 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
with open("redun_exec.json") as file:
redun_exec = json.loads(file.readline())
artifact.run.reference = redun_exec["id"]
artifact.run.reference_type = "redun_id"
artifact.run.save()

Map the redun run report¶
While lamindb auto-tracks the logs of the main python process you might also want to link the dedicated redun logs:
report = ln.Artifact(
"run_logs.txt",
description=f"Redun run report of {redun_exec['id']}",
run=False,
kind="__lamindb_run__", # mark as auxiliary artifact for the run
).save()
artifact.run.report = report
