Example of minting a minid with the minidtools R client

minids_from_R

# goal: mint minids for freeze 5 annotation in exchange area.

# requires digest and minidtools libraries

# computes checksum using local copy of the file
localPath <-
  paste0("/projects/topmed/variant_annotation/freeze_5/database/v0/",
         "parsed_files/2_snv.tsv.gz")

# use location on exchange area for the location metadata in the minid
eaPath <- 
  paste0("sftp://gap-upload.ncbi.nlm.nih.gov/exchange/Combined_Study_Data/",
         "Genotypes/freeze.5_annotation/WGSA_parsed/provisional/2_snv.tsv.gz")

# calculate the checksum
shaHash <- digest::digest(localPath, algo = "sha256", file = TRUE)

# load minid configuration
config <- minidtools::load_configuration(
  config_file = "~/.minid/minid-config.json")

# set up minid object
new_minid <- minidtools::minid()
minidtools::checksum_function(new_minid) <- "sha256"
minidtools::checksum(new_minid) <- shaHash
minidtools::titles(new_minid) <- list(list(title = "2_snv.tsv.gz"))
minidtools::locations(new_minid) <- list(list(link = eaPath))

# mint the new minid
minidtools::mint(minid = new_minid, configuration = config, test = TRUE)

# resolve the new minid to see the metadata:
minidtools::lookup("minid:b9g69w")
