bold accesses BOLD barcode data.
The Barcode of Life Data Systems (BOLD) is designed to support the generation and application of DNA barcode data. The platform consists of four main modules: a data portal, a database of barcode clusters, an educational portal, and a data collection workbench.
This package retrieves data from the BOLD database of barcode clusters, and allows for searching of over 1.7M public records using multiple search criteria including sequence data, specimen data, specimen plus sequence data, as well as trace files.
Documentation for the BOLD API: http://v4.boldsystems.org/index.php/api_home
See also the taxize book for more options for taxonomic workflows with BOLD: https://taxize.dev/
Installation
Installation instructions
Stable Version
install.packages("bold")Development Version
Install sangerseqR first if you’re planning on downloading and reading trace files. (The package is only used in the function bold::bold_read_trace())
For R < 3.5
source("http://bioconductor.org/biocLite.R")
biocLite("sangerseqR")For R >= 3.5
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("sangerseqR")Then install bold
remotes::install_github("ropensci/bold")Usage

Get trace files
This function downloads files to your machine - it does not load them into your R session - but prints out where the files are for your information.
traces1 <- bold_trace(ids = 'ACRJP618-11', progress = FALSE)
traces1

### Large data
Sometimes with `bold_seq()`, `bold_seqspec()` and `bold_specimen()` you request a lot of data, which can cause problems due
to BOLD's servers.
An example is the taxonomic name _Arthropoda_. When you send a request like
`bold_seq(taxon = "Arthropoda")`, `bold_seqspec(taxon = "Arthropoda")` or `bold_specimen(taxon = "Arthropoda")` BOLD attempts to give you back sequences and/or specimen information for all records under _Arthropoda_. This, as you can imagine, is a lot of sequences.
```r
library("taxize")Using taxize::downstream get children of Arthropoda
x <- downstream("Arthropoda", db = "ncbi", downto = "class")
#> ══ 1 queries ═══════════════
#> ✔ Found: Arthropoda
#> ══ Results ═════════════════
#>
#> ● Total: 1
#> ● Found: 1
#> ● Not Found: 0
nms <- x$Arthropoda$childtaxa_nameOptionally, check that the name exists in BOLD’s data. Any that are not in BOLD will give back a row of NAs
checks <- bold_tax_name(nms)
# all is good
checks[,1:5]
#> taxid taxon tax_rank tax_division parentid
#> 1 26059 Pycnogonida class Animalia 20
#> 2 63 Arachnida class Animalia 20
#> 3 74 Merostomata class Animalia 20
#> 4 493944 Pauropoda class Animalia 20
#> 5 80390 Symphyla class Animalia 20
#> 6 85 Diplopoda class Animalia 20
#> 7 75 Chilopoda class Animalia 20
#> 8 82 Insecta class Animalia 20
#> 9 372 Collembola class Animalia 20
#> 10 734357 Protura class Animalia 20

#> 16 889450 Ichthyostraca class Animalia 20
#> 17 NA <NA> <NA> <NA> NA
#> 18 80 Ostracoda class Animalia 20Then pass those names to bold_seq(). You could pass all names in at once, but we’re trying to avoid the large data request problem here, so run each one separately with lapply or a for loop like request.
