Code Ocean Aux Tools

License Code Style

Convenience tools for working in Code Ocean capsules and pipelines.


Background

These convenience tools were created to make working with files common in bioinformatics more streamlined. Some of the tools in this package are only useful in the Code Ocean platform but many of these tools will be useful outside of the platform.


Requirements

Python>=3.8


Installing Code Ocean Aux Tools in your capsule

Add the following package using pip in the environment UI Code-Ocean-Aux-Tools or use the following command at the terminal.

pip install Code-Ocean-Aux-Tools

Code-Ocean-Aux-Tools on Pypi


List of Available Commands

The following commands will work at the terminal or in a bash script. Each of these commands has a --help flag which provides more information about using the command.

- get_cpu_count
- get_dir_contents
- get_fasta_file
- get_fastq_pair
- get_fastqs
- get_groups
- get_pipeline_confirm
- get_read_direction
- get_read_pattern
- get_read_prefix
- get_rev_file
- set_log_msg

List of Available Python Functions

There are 2 modules you can import (co_utils & co_fastq) At the top of your python script, import them

from co_tools import co_utils
from co_tools import co_fastq

co_utils

- get_cpu_limit()
- get_dir_contents()
- get_groups()
- is_pipeline()

co_fastq

- get_fastq_pair()
- get_fastqs()
- get_read_direction()
- get_read_pattern()
- get_prefix()
- get_rev_file()

Logging

There is a pre-configured logger that will work seamlessly in bash and/or python and output to the same log file. The format for each log entry is:

[{Date} {Time} - {filename}:{funcName}:{lineno} - {Log Level}] {log message}

The available log levels are debug, info, warning, error, and critical

Python

To use the logger in a python script just import it and use it

from co_tools.get_logger import LOGGER

To use it just type LOGGER.{log level}("your log message here") where {log level} is your desired log level.

e.g. LOGGER.info("logging is fun")

Bash

To use the logger in a bash script, just use the set_log_msg command. It takes 1 required argument and an additional optional flag --log-level

The required argument is the log message and the optional flag is for the desired log level. The default log level is "WARNING" when no flag is used.

e.g. set_log_msg "logging is fun" --log-level "INFO"


Configuring the LOGGER

Activating the LOGGER

The Code Ocean LOGGER is turned off by default. To turn it on, just assign the log level, described in the next section.

Assigning the log level

Create an environment variable called CO_LOG_LEVEL and assign it one of the 5 available log levels. One method can be to assign the value to CO_LOG_LEVEL in your runscript (run) just before the entry script is executed.

e.g.

export CO_LOG_LEVEL="INFO"
python -u main.py "$@"

or

export CO_LOG_LEVEL="INFO"
bash main.sh "$@"

Logging to the console

By default, anytime a log message with level error or above is logged, the logger will create an entry in the log files with the log message and also print the log message to the console. If you would like the logger to always print the log message to the console whenever the logger creates an entry in the log file, then create an environment variable called CO_LOG_CONSOLE and assign its value to true.

export CO_LOG_CONSOLE="true"
export CO_LOG_LEVEL="INFO"
bash main.sh "$@"

Code Ocean is a cloud-based dry lab for scientific computing with a focus on guaranteeing reproducibility, collaboration and organizing scientific projects. Code Ocean automates best practices allowing users of the platform to focus on science yet follow best practices. Visit our Open Science Library for free code and to demo our free product.
