PMScanR is an R package for the large-scale identification, analysis, and visualization of protein motifs. It integrates PROSITE's ps_scan tool, handles data conversion, and offers multiple visualization methods, including heatmaps and sequence logos. The package also features a full graphical user interface (GUI) via Shiny for a code-free experience.

Once the package is accepted to Bioconductor, you will install it by starting R (version "4.4" or higher) and entering:

if (!require("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("PMScanR")

You can either launch the interactive application or run an analysis via the command line.

For a user-friendly, clickable interface that covers the entire analysis workflow, simply run:

library(PMScanR)
runPMScanRShiny()

library(PMScanR)

# 1. Get path to the example FASTA file included with the package
fasta_file <- system.file("extdata", "hemoglobins.fasta", package = "PMScanR")

# 2. Run the motif scan and save results in GFF format
runPsScan(in_file = fasta_file, out_format = 'gff', out_file = "results_scan.gff")
