kkonganti@1: # bettercallsal_db
kkonganti@1:
kkonganti@1: `bettercallsal_db` is an end-to-end automated workflow to generate and consolidate the required DB flat files based on [NCBI Pathogens Database for Salmonella](https://ftp.ncbi.nlm.nih.gov/pathogen/Results/Salmonella/). It first downloads the metadata based on the provided release identifier (Ex: `latest_snps` or `PDG000000002.2537`) and then creates a `mash sketch` based on the filtering strategy. It generates two types of sketches, one that prioritizes genome collection based on SNP clustering (`per_snp_cluster`) and the other just collects up to N number of genome accessions for each `computed_serotype` column from the metadata file (`per_computed_serotype`).

kkonganti@1: The `bettercallsal_db` workflow should finish within an hour with stable internet connection.

kkonganti@1: ## Workflow Usage
kkonganti@1:
kkonganti@1: ```bash
kkonganti@1: cpipes --pipeline bettercallsal_db [options]
kkonganti@1: ```
kkonganti@1:
kkonganti@1: \
kkonganti@1:
kkonganti@1:
kkonganti@1: Example: Run the `bettercallsal_db` pipeline and store output at `/data/Kranti_Konganti/bettercallsal_db`.
kkonganti@1:
kkonganti@1: ```bash
kkonganti@1: cpipes
kkonganti@1: --pipeline bettercallsal_db \
kkonganti@1: --pdg_release PDG000000002.2537 \
kkonganti@1: --output /data/Kranti_Konganti/bettercallsal_db
kkonganti@1: ```
kkonganti@1:
kkonganti@1: \
kkonganti@1:
kkonganti@1:
kkonganti@1: Now you can run the `bettercallsal` workflow with the created database by mentioning the root path to the database with `--bcs_root_dbdir` option.
kkonganti@1:
kkonganti@1: ```bash
kkonganti@1: cpipes
kkonganti@1: --pipeline bettercallsal \
kkonganti@1: --input /path/to/illumina/fastq/dir \
kkonganti@1: --output /path/to/output \
kkonganti@1: --bcs_root_dbdir /data/Kranti_Konganti/bettercallsal_db
kkonganti@1: ```
kkonganti@1:

kkonganti@1: ## Note
kkonganti@1:
kkonganti@1: Please note that the last step of the `bettercallsal_db` workflow named `SCAFFOLD_GENOMES` will spawn multiple processes and is not cached by **Nextflow**. This is an intentional setup for this specific stage of the workflow to speed up database creation and as such it is recommended that you run this workflow in a grid computing or similar cloud computing setting.

kkonganti@1: . Default: false
kkonganti@1:
kkonganti@1: --mashsketch_z : Alphabet to base hashes on (case

kkonganti@1: mers with other characters will be ignored
kkonganti@1: . Implies --mashsketch_n. Default: false
kkonganti@1:
kkonganti@1: --mashsketch_Z : Preserve case in k-mers and alphabet (case
