# surfaltr Surface proteins are hydrophobic and remain difficult to study thereby necessitating the use of TM topology prediction methods such as TMHMM (1) and Phobius (2). However, there exists a need for bioinformatic approaches to streamline batch processing of isoforms for comparing and visualizing topologies. To address this gap, we have developed an R package, SurfaltR. It pairs inputted isoforms, either known alternatively spliced or novel, with their APPRIS (3) annotated principal counterparts, predicts their TM topologies using TMHMM or Phobius, and generates a customizable graphical output. Further, SurfaltR facilitates the prioritization of biologically diverse isoform pairs through the incorporation of three different ranking metrics and through protein alignment functions. # Note: If you use surfaltr in published research, please cite the Bioconductor R package and possibly a subsequent publication (will be updated later). # Installation: As surfaltr is hosted on Bioconductor, please follow installation instructions outlined here: # Please refer to the vignette for detailed descriptions of installation, workflow, functions and troubleshooting. # References 1.
