The alabaster.string package implements methods for saving and loading XStringSet objects under the alabaster framework.
It provides a language-agnostic method for serializing biological sequences along with any sequence-specific metadata.
To get started, install the package and its dependencies from Bioconductor:
# install.packages("BiocManager")BiocManager::install("alabaster.string")In the example below, we save a QualityScaledDNAStringSet object to file:
library(Biostrings)
example(QualityScaledDNAStringSet, echo=FALSE) # can't be bothered to copy it here.qdna1## A QualityScaledDNAStringSet instance containing:## ## DNAStringSet object of length 2:## width seq## [1] 4 TTGA## [2] 4 CTCN## ## PhredQuality object of length 2:## width seq## [1] 4 *+,-## [2] 4 6789
library(alabaster.string)
tmp<- tempfile()
saveObject(qdna1, tmp)
roundtrip<- readObject(tmp)
class(roundtrip)
