Documentation

Here's a brief documentation. Trailblazer functionality can be accessed from the command line interface (CLI), the monitoring web interface, the supporting REST API, as well as using the Python API.

Command line interface

Command: trailblazer init

Setup (or reset) a Trailblazer database. The command will set up all the tables in the database. You can reset an existing database by using the --reset option.

trailblazer --database "sqlite:///tb.sqlite3" init --reset
Delete existing tables? [analysis, info, job, user] [y/N]: y
Success! New tables: analysis, info, job, user

Command: trailblazer user

This command can be used both to add a new user to the database (and give them access to the web interface) and view information about an existing user.

# add a new user
trailblazer user --name "Paul Anderson" [e-mail]
New user added: [e-mail] (2)

# check an existing user
trailblazer user [e-mail]
{'created_at': datetime.datetime(2017, 6, 22, 8, 49, 44, 685977), 'google_id': None, 'name': 'Paul Anderson', 'email': '[e-mail]', 'avatar': None, 'id': 2}

Command: trailblazer archive-user

This command archives a user in the database (and removes their access to the web interface).

# archive a user
trailblazer archive-user [e-mail]
User archived: [e-mail]

Command: trailblazer users

This command can be used both to list all users in the database and get a filtered list of users.

# list all users
trailblazer users
Listing users in database:
{'created_at': datetime.datetime(2017, 6, 22, 8, 49, 44, 685977), 'google_id': None, 'name': 'Paul Anderson', 'email': '[e-mail]', 'avatar': None, 'id': 2}

# list all users named 'Anderson' that has an email with 'magnolia' in it
trailblazer users --name Anderson --email magnolia
Listing users in database:
{'created_at': datetime.datetime(2017, 6, 22, 8, 49, 44, 685977), 'google_id': None, 'name': 'Paul Anderson', 'email': '[e-mail]', 'avatar': None, 'id': 2}

Command: trailblazer log

Logs the status of a run to the supporting database. You need to point to the analysis config of a specific run.

trailblazer log path/to/case/analysis/case_config.yaml

You can point to the same analysis multiple times, Trailblazer will detect if the same analysis has been added before and skip it if no information has been updated. If an analysis has been added previously as "running" or "pending", those entries will automatically be removed as soon as the same analysis is logged as either "completed" or "failed".

Command: trailblazer scan

Convenience command to scan an entire directory structure for all analyses and update their status in one go. Assumes the base directory consists of individual case folders:

trailblazer scan /path/to/analyses/dir/

This command can easily be setup in a crontab to run e.g. every hour and keep the analysis statuses up-to-date!

Command: trailblazer ls

Prints the case id for the most recently completed analyses to the console.

trailblazer ls
F0013487
F0013362
F0006106
17083
F0013469
17085

Command: trailblazer delete

Deletes an analysis log from the database. The input is the unique analysis id which is printed ones the analysis is initially logged. It's also displayed in the web interface.

trailblazer delete 4
