scpdata 1.13.0
scpdata packagescpdata disseminates mass spectrometry (MS)-based single-cell
proteomics (SCP) data sets formatted using the scp data structure.
The data structure is described in the
scp vignette.
In this vignette, we describe how to access the SCP data sets. To
start, we load the scpdata package.
library("scpdata")ExperimentHubThe data is stored using the
ExperimentHub
infrastructure. We first create a connection with ExperimentHub.
eh <- ExperimentHub()You can list all data sets available in scpdata using the query
function.
query(eh, "scpdata")
#> ExperimentHub with 26 records
#> # snapshotDate(): 2024-10-24
#> # $dataprovider: MassIVE, PRIDE, SlavovLab website, Dataverse
#> # $species: Homo sapiens, Mus musculus, Rattus norvegicus, Gallus gallus
#> # $rdataclass: QFeatures
#> # additional mcols(): taxonomyid, genome, description,
#> # coordinate_1_based, maintainer, rdatadateadded, preparerclass, tags,
#> # rdatapath, sourceurl, sourcetype
#> # retrieve records with, e.g., 'object[["EH3899"]]'
#>
#> title
#> EH3899 | specht2019v2
#> EH3900 | specht2019v3
#> EH3901 | dou2019_lysates
#> EH3902 | dou2019_mouse
#> EH3903 | dou2019_boosting
#> ... ...
#> EH9450 | gregoire2023_mixCTRL
#> EH9477 | khan2023
#> EH9487 | guise2024
#> EH9497 | petrosius2023_mES
#> EH9498 | petrosius2023_AstralAMLAnother way to get information about the available data sets is to
call scpdata(). This will retrieve all the available metadata. For
example, we can retrieve the data set titles along with the
description to make an informed choice about which data set to choose.

To get one of the data sets (e.g. dou2019_lysates) you can either
retrieve it using the ExperimentHub query function
scp <- eh[["EH3901"]]
#> see ?scpdata and browseVignettes('scpdata') for documentation
#> loading from cache
scp

(e.g. ?dou2019_lysates). You can find information about the data
content, the acquisition protocol, the data collection procedure as
well as the data sources and reference.
For more information about manipulating the data sets, check the
scp
package. The scp
vignette
will guide you through a typical SCP data processing workflow. Once
your data is loaded from scpdata you can skip section 2
