OrthoEvol 1.0.0b2

This package aids in the analysis of orthologous genes.

OrthoEvolution

OrthoEvolution is an easy to use and comprehensive Python package which aids in the analysis and visualization of comparative evolutionary genetics related projects such as the inference of orthologs.

Current Version: 1.0.0b2

Overview

This package focuses on inferring orthologs using NCBI's blast, various sequence alignment strategies, and phylogenetics analyses including PAML, PhyML, ete3, and more tools.

Ultimately, the goal of this project is to create a reusable pipeline for the inference of orthologs in order to ensure reproducibility of data as well as improve the management and analysis of (what can be) large datasets. The Cookies, Manager, Pipeline, and Tools modules act as a framework for our workflow, while the Orthologs module provides access to specific functions for our various ortholog inference projects.

Running a pre-configured local blast

from OrthoEvol.Orthologs.Blast import OrthoBlastN

# Use an existing list of gpcr genes
gpcr_blastn = OrthoBlastN(project="orthology-gpcr", method=1,
                         save_data=True, acc_file="gpcr.csv", 
                         copy_from_package=True)

# Run blast
gpcr_blastn.run()

Simple project creation

from OrthoEvol.Manager.management import ProjectManagement

ProjectManagement(repo="test-repo", user=None,
                  project="test-project",
                  research=None,
                  research_type='comparative_genetics',
                  new_repo=False, new_user=False, new_project=True,
                  new_research=False)

Simple blast database downloading

from OrthoEvol.Tools.ftp import NcbiFTPClient

ncbiftp = NcbiFTPClient(email='[e-mail]')
ncbiftp.getblastdb(database_name='refseq_rna', v5=True)

Creating projects and databases dynamically

from OrthoEvol.Manager.management import ProjectManagement
from OrthoEvol.Manager.database_dispatcher import DatabaseDispatcher
from OrthoEvol.Manager.config import yml
from pkg_resources import resource_filename
from pathlib import Path
import yaml
import getpass
from datetime import datetime as d
import os

# Define job name
job_name = "jobname"

# Function to load configuration from YAML file
def load_config(file_name):
    file_path = resource_filename(yml.__name__, file_name)
    with open(file_path, 'r') as file:
        return yaml.load(file, Loader=yaml.FullLoader)

# Load project management configuration
pm_config = load_config("initialize_new.yml")
project_manager = ProjectManagement(**pm_config["Management_config"])

# Load and update database management configuration
db_config = load_config("databases.yml")
db_config.update(pm_config)

# Configure NCBI RefSeq release settings
ncbi_config = db_config['Database_config']['Full']['NCBI']['NCBI_refseq_release']
ncbi_config['upload_number'] = 12
ncbi_config['pbs_dict'] = {
    'author': getpass.getuser(),
    'description': 'This is a default pbs job.',
    'date': d.now().strftime('%a %b %d %I:%M:%S %p %Y'),
    'proj_name': 'OrthoEvol',
    'select': '1',
    'memgb': '6gb',
    'cput': '72:00:00',

    'pbsworkdir': os.getcwd(),
    'cmd': f'python3 {os.path.join(os.getcwd(), job_name + ".py")}',
    'email': 'n/a'
}

# Save the updated configuration to a YAML file
config_file_path = project_manager.user_log / Path("upload_config.yml")
with open(str(config_file_path), 'w') as config_file:
    yaml.dump(db_config, config_file, default_flow_style=False)

# Initialize database dispatcher and execute dispatch functions
db_dispatcher = DatabaseDispatcher(config_file_path, project_manager)
db_dispatcher.dispatch(db_dispatcher.strategies, db_dispatcher.dispatcher, db_dispatcher.configuration)
