auto_seq_download: Automatic Sequence Download

In MACER: Molecular Acquisition, Cleaning, and Evaluation in R 'MACER'

Automatic Sequence Download

Description

Takes a list of genera, as supplied by the user, and searches and downloads molecular sequence data from BOLD and Genbank.

Usage

auto_seq_download(
  BOLD_database = TRUE,
  NCBI_database = TRUE,
  search_str = NULL,
  input_file = NULL,
  output_file = NULL,
  seq_min = 100,
  seq_max = 2500
)

Arguments

BOLD_database	TRUE is to include, FALSE is to exclude; default TRUE
NCBI_database	TRUE is to include, FALSE is to exclude; default TRUE
search_str	NULL uses the default string, anything other than NULL then that string will be used for the GenBank search; default NULL. The Default String is: (genus[ORGN]) NOT (shotgun[ALL] OR genome[ALL] OR assembled[ALL] OR microsatellite[ALL])
input_file	NULL prompts the user to indicate the location of the input file through point and click prompts, anything other than NULL then the string supplied will be used for the location; default NULL
output_file	NULL prompts the user to indicate the location of the output file through point and click prompts, anything other than NULL then the string supplied will be used for the location; default NULL
seq_min	holds the minimum length value to not flag the sequence; default 100
seq_max	holds the maximum length value to not flag the sequence; default 2500

Details

User Input: A list of genera in a text file in a single column with a new line at the end of the list.

Value

Outputs: One main folder containing three other folders. Main folder - Seq_auto_dl_TTTTTT_MMM_DD Three subfolders: 1. BOLD - Contains a file for every genus downloaded with the raw data from the BOLD system. 2. NCBI - Contains a file for every genus downloaded with the raw data from GenBank. 3. Total_tables - Contains files for the running of the function which include... A_Summary.txt - This file contains information about the downloads. A_Total_Table.tsv - A file with a single table containing the accumulated data for all genera searched.

Note

When using a custom search string for NCBI only a single genus at a time can be used.
