Instances

Instances#

An instance is a single execution of a workflow. Each instance gets a unique auto-generated name based on adjective-animal pairs, such as brave-lion, swift-otter, or calm-raven.

Instances page#

Open the Instances page from the left sidebar (the storage icon). It lists all workflow instances in a table with these columns:

Column

Description

Status

Colour-coded icon: running (blue), completed (green), failed (red), created (grey), closed (grey).

Instance

The auto-generated name of the instance.

Workflow

The workflow name and version (e.g. amplicon-nf@latest).

Actions

Delete button to remove the instance.

The list auto-refreshes every 5 seconds.

Viewing instance details#

Click the status icon of any instance to open its detail page. Depending on the instance status you will see either:

  • The Parameters page — for instances with status created (allows reconfiguration before launch).

  • The Monitor page — for instances with status running, completed, or failed.

Deleting an instance#

Use the Delete button in the Actions column. If the instance is still running, GLACIER will kill the processes first. This removes the instance directory and all its contents (work directory, logs, reports, parameters).

Deleting a completed instance is safe — your pipeline outputs should be moved elsewhere first if you want to keep them.

Instance directory layout#

Each instance is stored at:

<documentsPath>/instances/<owner>/<repo>@<version>/<instance_name>/

params.json        -- Parameters used for the run
stdout.log         -- Nextflow standard output
stderr.log         -- Nextflow standard error
nextflow.log       -- Nextflow internal log
work/              -- Nextflow work directory (per-task outputs)
<reports>          -- HTML report files (e.g. articMinIONReport.html)
