The ExperimentHub server provides easy R / Bioconductor access to
large files of data.
The ExperimentHub package provides a client interface to resources stored at the ExperimentHub web service. It has similar functionality to AnnotationHub package.
library(ExperimentHub)The ExperimentHub package is straightforward to use.
Create an ExperiemntHub object
eh = ExperimentHub()## updating metadata: retrieving 1 resource
## snapshotDate(): 2018-04-27Now at this point you have already done everything you need in order
to start retrieving experiment data. For most operations, using the
ExperimentHub object should feel a lot like working with a familiar
list or data.frame and has all of the functionality of an Hub
object like AnnotationHub package’s AnnotationHub
object.
Lets take a minute to look at the show method for the hub object eh

You can see where the data is coming from (dataprovider), as well as what species have samples present (species), what kinds of R data objects could be returned (rdataclass). We can take a closer look at all the kinds of data providers that are available by simply looking at the contents of dataprovider as if it were the column of a data.frame object like this:

## [78] "ICGC"
## [79] "Private"In the same way, you can also see data from different species inside the hub by looking at the contents of species like this:
head(unique(eh$species))## [1] "Homo sapiens" "Mus musculus"
## [3] "Homo Sapiens" "Mus musculus (E18 mice)"
## [5] "Mus Musculus (E18 mice)" "Mus Musculus"And this will also work for any of the other types of metadata present. You can learn which kinds of metadata are available by simply hitting the tab key after you type ‘eh$’. In this way you can explore for yourself what kinds of data are present in the hub right from the command line. This interface also allows you to access the hub programatically to extract data that matches a particular set of criteria.
Another valuable types of metadata to pay attention to is the rdataclass.
head(unique(eh$rdataclass))## [1] "ExpressionSet" "GAlignmentPairs"
## [3] "CellMapperList" "gds.class"
## [5] "RangedSummarizedExperiment" "GRanges"The rdataclass allows you to see which kinds of R objects the hub will return to you. This kind of information is valuable both as a means to filter results and also as a means to explore and learn about some of the kinds of experimenthub objects that are widely available for the project. Right now this is a pretty short list, but over time it should grow as we support more of the different kinds of experimenthub objects via the hub.
Now lets try getting the data files associated with the r Biocpkg("alpineData") package using the query method. The query method lets you
search rows for specific strings, returning an ExperimentHub instance with
just the rows matching the query. The preparerclass column of metadata
monitors which package is associated with the ExperimentHub data.
One can get chain files for Drosophila melanogaster from UCSC with:
apData <- query(eh, "alpineData")
apData## ExperimentHub with 4 records
## # snapshotDate(): 2018-04-27
## # $dataprovider: GEUVADIS
## # $species: Homo sapiens
## # $rdataclass: GAlignmentPairs
## # additional mcols(): taxonomyid, genome, description,
## # coordinate_1_based, maintainer, rdatadateadded, preparerclass,
## # tags, rdatapath, sourceurl, sourcetype
## # retrieve records with, e.g., 'object[["EH166"]]'
##
## title
## EH166 | ERR188297
## EH167 | ERR188088
## EH168 | ERR188204
## EH169 | ERR188317Query has worked and you can now see that the only data present is provided by the “alpineData”.
The metadata underlying this hub object can be retrieved by you
apData$preparerclass## [1] "alpineData" "alpineData" "alpineData" "alpineData"df <- mcols(apData)By default the show method will only display the first 5 and last 5 rows. There are hundreds of records present in the hub.
length(eh)## [1] 1192Lets look at another example, where we pull down only data from the hub for species “mus musculus”.

## seqinfo: 194 sequences from an unspecified genomeEach file is retrieved from the ExperimentHub server and the file is also cache locally, so that the next time you need to retrieve it, it should download much more quickly.
ExperimentHub objectsWhen you create the ExperimentHub object, it will set up the object
for you with some default settings. See ?ExperimentHub for ways to
customize the hub source, the local cache, and other instance-specific
options, and ?getExperimentHubOption to get or set package-global
options for use across sessions.
If you look at the object you will see some helpful information about it such as where the data is cached and where online the hub server is set to.
