signalHsmm (version 1.3)

run_signalHsmm: Predict presence of signal peptide in protein

Description

Using the hidden semi-Markov model predict presence of signal peptide in eukaryotic proteins.

Usage

run_signalHsmm(test_data)

Arguments

test_data

single protein sequence (character vector) or list of sequences. It may be an object of class SeqFastaAA.

Value

• An object of class hsmm_pred_list.

Details

Function signalHsmm returns respectively probability of presence of signal peptide, start of signal peptide and the probable cleavage site localization. If input consists of more than one sequence, result is a data.frame where each column contains above values for different proteins.

Examples

#run signalHsmm on one sequence
x1 <- run_signalHsmm(benchmark_dat[[1]])

#run signalHsmm on one sequence, but input is a character vector
