Recent studies highlight the crucial regulatory roles of transposable elements (TEs) on proximal gene expression in distinct biological contexts such as disease and development. However, computational tools extracting potential TE - proximal gene expression associations from RNA-sequencing data are still missing. Implementation. Herein, we developed a novel R package, using a linear regression model, for studying the potential influence of TE species on proximal gene expression from a given RNA-sequencing data set. Our R package, namely TEffectR, makes use of publicly available RepeatMasker TE and Ensembl gene annotations as well as several functions of other R-packages. It calculates total read counts of TEs from sorted and indexed genome aligned BAM files provided by the user, and determines statistically significant relations between TE expression and the transcription of nearby genes under diverse biological conditions.eninfo:eu-repo/semantics/openAccessTransposable elementsGene regulationGene expressionRegressionLinear modelR packageIn-SituBreastDnaTranscriptomeMutationCellsFen1Article10.7717/peerj.81922-s2.0-85076368007
