relecov-tools

THIS REPO IS UNDER ACTIVE DEVELOPMENT.

relecov-tools is a set of helper tools for the assembly of the different elements in the RELECOV platform (Spanish Network for genomic surveillance of SARS-Cov-2) as data download, processing, validation and upload to public databases, as well as analysis runs and database storage.

download

The command download connects to a transfer protocol (currently sftp) and downloads all files in the different available folders in the passed credentials. In addition, it checks if the files in the current folder match the files in the metadata file and also checks if there are md5sum for each file. Else, it creates one before storing in the final repository.

$ relecov-tools download --help
Usage: relecov-tools download [OPTIONS]

  Download files located in sftp server.

  Options:
    -u, --user            User name for login to sftp server
    -p, --password        Password for the user to login
    -d, --download_option Select the download option: [download_only, download_clean, delete_only].
        download_only will only download the files
        download_clean will remove files from sftp after download
        delete_only will only delete the files
    -o, --output_location Flag: Select location for downloaded files, overrides config file location
    -t, --target_folders  Flag: Select which sftp folders will be targeted giving [paths] or via prompt
    -f, --conf_file       Configuration file in yaml format (no params file)
    --help                Show this message and exit.

Configuration can be passed in several formats:

• if no config_file is passed, default values are fetched from conf/configuration.json, and user and password are asked in prompt.
• Default values can be overwritten using a yml config file, so you can input user, password, sftp_server, etc.

Config file example with all available options:

sftp_server: "sftprelecov.isciii.es"
sftp_port: "22"
sftp_user : "user"
sftp_passwd : "pass"
storage_local_folder: "/tmp/relecov"

Mandatory Fields

Ensure that the fields below are properly defined as headers in your Excel sheet (database definition):

enum: List of possible values for enumeration.
examples: Example values for the property.
ontology_id: Identifier for ontology.
type: Data type of the property (e.g., string, integer).
description: Description of the property.
classification: Classification or category of the property.
label_name: Label or name for the property.

complex_field (Y/N): Indicates if the property is a complex (nested) field (Y) or a standard field (N).

custom logs

After executing each of these modules, you may find a custom log report in json format named "DATE_EXECUTED-MODULE_log_summary.json. These custom log summaries can be useful to detect errors in metadata in order to fix them and/or notify the users.

Python package mode

relecov-tools is designed in a way that you can use import the different modules and use them in your own scripts, for example:

import relecov_tools.sftp_handle
user="admin"
passwd="1234"
conf_file="/path/to/conf"

sftp_connection = relecov_tools.sftp_handle.SftpHandle(
    user, password, conf_file
)
sftp_connection.download()

DOCs soon!!
