biomartr 1.0.0

New Functions

  • New function check_annotation_biomartr() helps to check whether downloaded GFF or GTF files are corrupt. Find more details here

  • new function getCollectionSet() allows users to retrieve a Collection: Genome, Proteome, CDS, RNA, GFF, Repeat Masker, AssemblyStats of multiple species

Example:

# define scientific names of species for which
# collections shall be retrieved
organism_list <- c("Arabidopsis thaliana", 
                   "Arabidopsis lyrata", 
                   "Capsella rubella")
# download the collection of Arabidopsis thaliana from refseq
# and store the corresponding genome file in '_ncbi_downloads/collection'
 getCollectionSet( db       = "refseq", 
             organism = organism_list, 
             path = "set_collections")

New Features

  • the getGFF() function receives a new argument remove_annotation_outliers to enable users to remove corrupt lines from a GFF file Example:
Ath_path <- biomartr::getGFF(organism = "Arabidopsis thaliana", remove_annotation_outliers = TRUE)

  • the getGFFSet() function receives a new argument remove_annotation_outliers to enable users to remove corrupt lines from a GFF file

  • the getGTF() function receives a new argument remove_annotation_outliers to enable users to remove corrupt lines from a GTF file

  • adding a new message system to biomartr::organismBM(), biomartr::organismAttributes(), and biomartr::organismFilters() so that large API queries don't seem so unresponsive

  • getCollection() receives new arguments release, remove_annotation_outliers, and gunzip that will now be passed on to downstream retrieval functions

biomartr 0.9.2

  • minor changes to comply with CRAN policy regarding Internet access failure -> Instead of using warnings or error messages, only gentle messages are allowed to be used

biomartr 0.9.0

Please be aware that as of April 2019, ENSEMBLGENOMES was retired (see details here). Hence, all biomartr functions were updated and won't support data retrieval from ENSEMBLGENOMES servers anymore.

New Functions

  • New function clean.retrieval() enables formatting and automatic unzipping of meta.retrieval output (find out more here: https://docs.ropensci.org/biomartr/articles/MetaGenome_Retrieval.html#un-zipping-downloaded-files)
  • New function getGenomeSet() allows users to easily retrieve genomes of multiple specified species. In addition, the genome summary statistics for all retrieved species will be stored as well to provide users with insights regarding the genome assembly quality of each species. This file can be used as Supplementary Information file in publications to facilitate reproducible research.
  • New function getProteomeSet() allows users to easily retrieve proteomes of multiple specified species
  • New function getCDSSet() allows users to easily retrieve coding sequences of multiple specified species
  • New function getGFFSet() allows users to easily retrieve GFF annotation files of multiple specified species
  • New function getRNASet() allows users to easily retrieve RNA sequences of multiple specified species
  • New function summary_genome() allows users to retrieve summary statistics for a genome assembly file to assess the influence of genome assembly qualities when performing comparative genomics tasks
  • New function summary_cds() allows users to retrieve summary statistics for a coding sequence (CDS) file. We noticed, that many CDS files stored in NCBI or ENSEMBL databases contain sequences that aren't divisible by 3 (division into codons). This makes it difficult to divide CDS into codons for e.g. codon alignments or translation into protein sequences. In addition, some CDS files contain a significant amount of sequences that do not start with AUG (start codon). This function enables users to quantify how many of these sequences exist in a downloaded CDS file to process these files according to the analyses at hand.

New Features of Existing Functions

  • the default value of argument reference in meta.retrieval() changed from reference = TRUE to reference = FALSE. This way all genomes (reference AND non-reference) genomes will be downloaded by default. This is what users seem to prefer.
  • getCollection() now also retrieves GTF files when db = 'ensembl'
  • getAssemblyStats() now also performs md5 checksum test
  • all md5 checksum tests now retrieve the new md5checkfile format from NCBI RefSeq and Genbank
  • getGTF(): users can now specify the NCBI Taxonomy ID or Accession ID in addition to the scientific name in argument 'organism' to retrieve genome assemblies
  • getGFF(): users can now specify the NCBI Taxonomy ID or Accession ID for ENSEMBL in addition to the scientific name in argument 'organism' to retrieve genome assemblies
  • getMarts() will now throw an error when BioMart servers cannot be reached (#36)
  • getGenome() now also stores the genome summary statistics (see ?summary_genome()) for the retrieved species in the documentation folder to provide users with insights regarding the genome assembly quality
  • In all get*() functions the default for argument reference is now set from reference = TRUE to reference = FALSE (= new default)
  • all get*() functions now received a new argument release which allows users to retrieve specific release versions of genomes, proteomes, etc from ENSEMBL and ENSEMBLGENOMES
  • all get*() functions received two new arguments clean_retrieval and gunzip which allows users to upzip the downloaded files directly in the get*() function call and rename the file for more convenient downstream analyses

biomartr 0.4.0

Bug fixes

  • fixing a major bug ropensci#6 that caused that in all get*() (genome, proteome, gff, etc.) and meta.retrieval*() functions the meta retrieval process errored and terminated whenever NCBI or ENSEMBL didn't store all types of sequences for a particular organism: genome, proteome, cds, etc. This has been fixed now and function calls such as meta.retrieval(kingdom = "bacteria", db = "genbank", type = "proteome") should work properly now (Thanks to @ARamesh123 for making me aware if this bug). Hence, this bug affected all attempts to download all proteome sequences e.g. for bacteria and viruses, because NCBI does not store genome AND proteome information for all bacterial or viral species.

New Functions

  • new function getAssemblyStats() allows users to retrieve the genome assembly stats file from NCBI RefSeq or Genbank, e.g. ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/000/001/405/GCF_000001405.36_GRCh38.p10/GCF_000001405.36_GRCh38.p10_assembly_stats.txt

Function changes

  • meta.retrieval() and meta.retrieval.all() can now also download genome assembly stats for all selected species

  • meta.retrieval() receives a new argument group that allows users to retrieve species belonging to a subgroup instead of the entire kingdom. Available groups can be retrieved with getGroups().

  • functions getSubgroups() and listSubgroups() have been removed and their initial functionality has been merged and integrated into getGroups() and listGroups()

  • listGroups() receives a new argument details that allows users to retrieve the organism names that belong to the corresponding subgroups

  • getGroups() is now based on listGroups()

  • internal function getGENOMESREPORT() is now exported and available to the user

  • all organism*() functions now also support Ensembl Plants, Ensembl Metazoa, Ensembl Protist, and Ensembl Fungi (Thanks for pointing out Alex Gabel)

  • getMarts() and getDatasets() now also support Ensembl Plants, Ensembl Metazoa, Ensembl Protist, and Ensembl Fungi (Thanks for pointing out Alex Gabel)

Vignette updates

biomartr 0.3.0

Bug fixes

  • Fixing a bug ropensci#2 based on the readr package that affected the getSummaryFile(), getKingdomAssemblySummary(), getMetaGenomeSummary(), getENSEMBL.Seq() and getENSEMBLGENOMES.Seq() functions causing quoted lines in the assembly_summary.txt to be omitted when reading these files. This artefact caused that e.g. instead of information of 80,000 Bacteria genomes only 40,000 (which non-quotations) were read (Thanks to Xin Wu).

biomartr 0.2.1

In this version of biomartr the organism*() functions were adapted to the new ENSEMBL 87 release in which organism name specification in the Biomart description column was changed from a scientific name convention to a mix of common name and scientific name convention.

  • all organism*() functions have been adapted to the new ENSEMBL 87 release organism name notation that is used in the Biomart description

  • fixing error handling bug that caused commands such as download.database(db = "nr.27.tar.gz") to not execute properly

biomartr 0.2.0
