biobtreeR 1.6.0
The biobtreeR package provides an interface to biobtree tool which allows mapping the bioinformatics datasets via identifiers and special keywors with simple or advance chain query capability.
library(biobtreeR)
# Create an folder and set as an output directory
# It is used for database and configuration files
# temporary directory is used for demonstration purpose
bbUseOutDir(tempdir())## [1] 0For mapping queries, biobtreeR use a database which stored in local storage. Database can be built 2 ways, first way is to retrieve pre built database. These database consist of commonly studied datasets and model organism and updated regularly following the major uniprot and ensembl data releases.
# Called once and saves the built in database to local disk
# Included datasets hgnc,hmdb,taxonomy,go,efo,eco,chebi,interpro
# Included uniprot proteins and ensembl genomes belongs to following organisms:
# homo_sapiens, danio_rerio(zebrafish), gallus_gallus(chicken), mus_musculus, Rattus norvegicus, saccharomyces_cerevisiae,
# arabidopsis_thaliana, drosophila_melanogaster, caenorhabditis_elegans, Escherichia coli, Escherichia coli str. K-12 substr. MG1655, Escherichia coli K-12
# Requires ~ 6 GB free storage
bbBuiltInDB()For the genomes which are not included in the pre built database can be built in local computer. All the ensembl and ensembl genomes organisms are supported. List of these genomes and their taxonomy identifiers can be seen from ensembl websites 1,2,3,4,5,6,
# multiple species genomes supported with comma seperated taxonomy identifiers
bbBuildCustomDB(taxonomyIDs = "1408103,206403")Once database is retrieved or built to local disk queries are performed via lightweight local server. Local server provide web interface for data expoloration in addition to the R functions for performing queries for R pipelines. Local server runs as a background process so both web interface and R functions can be used at the same time once it is started. While web server running web interface can be accessed via address http://localhost:8888/ui
bbStart()## [1] "/tmp/Rtmpf76BOw"

## 7 #Mapping and filtering queries are performed via bibobtree’s mapping query syntax which allowed chain mapping and filtering capability from identifiers to target identifiers or attributes. Mapping query syntax consist of single or multiple mapping queries in the format map(dataset_id).filter(Boolean query expression).map(...).filter(...)... and allow performing chain mapping among datasets. For mapping queries bbMapping function is used, for instance in following example, maps protein to its go terms and in the second query mapping has been done with filter.
bbMapping("AT5G3_HUMAN",'map(go)',attrs = "type")## mapping_id type

## 2 GO:0015986 biological_process
## 3 GO:0042407 biological_process
## 4 GO:0042776 biological_processIn the example for the first parameter single protein accession has been used but similar with bbSearch functions multiple identifers or keywords can be used. In the last query type attribute was used to filter mapping only with biological process go terms. Dataset attributes are used in the filters starts with their dataset name as in the above example it starts with go.
In order use in filter expressions, each datasets attributes lists with bbListAttrsfunction via sample identifier. For instance following query shows gene ontology attributes.
bbListAttrs("go")## [1] "type" "name" "[]synonyms"bbListAttrs("uniprot")## [1] "[]accessions" "[]genes" "[]names"
## [4] "[]alternative_names" "[]submitted_names" "sequence.seq"
## [7] "sequence.mass" "reviewed"In this section biobtreeR functionalities will be discussed in detail via gene and protein centric example use cases. For live demo of web interface including these use cases with additional chemistry centric use cases can be accessed via https://www.ebi.ac.uk/~tgur/biobtree/
Ensembl, Ensembl Genomes and HGNC datasets are used for gene related data. One of the most common gene related dataset identfiers are ensembl,hgnc,transcript,exon. Let’s start with listing their attiributes,
bbListAttrs("hgnc")## [1] "[]names" "[]symbols" "locus_group" "[]aliases"
## [5] "locus_type" "[]prev_names" "[]prev_symbols" "status"
## [9] "[]gene_groups"bbListAttrs("ensembl")## [1] "name" "description" "start" "end" "biotype"
## [6] "genome" "strand" "seq_region" "branch"bbListAttrs("transcript")## [1] "name" "start" "end" "biotype" "strand"
## [6] "seq_region" "utr5Start" "utr5End" "utr3Start" "utr3End"
## [11] "source"bbListAttrs("exon")## [1] "start" "end" "strand" "seq_region"bbListAttrs("cds")## [1] "start" "end" "strand" "seq_region" "frame"Note that there are several other gene related datasets without attributes and can be used in mapping queries such as probesets, genebank and entrez etc. Full dataset list can be discovered with bbListDatasets. Now lets build example mapping queries,

Built in function for genomic range queries
To simplfy previous use case query 3 builtin range query functions are provided. These functions are overlaps, within and covers. These functions can be used for ensembl, transcript, exon and cds
entries which have start and end genome coordinates. For instance previous query can be written following way with overlaps function which list all the overlapping genes in human with given range.
