⚠️There's a newer version (1.5) of this package.Take me there.

Predict Presence of Signal Peptides

signalHsmm predicts presence of signal peptides in eukaryotic proteins using hidden semi-Markov models. The implemented algorithm can be accessed as a web-based service www.smorfland.uni.wroc.pl/signalHsmm

Local instance of signalHsmm

signalHsmm can be also used locally as the R package. It can be installed from CRAN using:

install.packages("signalHsmm")

You can install the latest development version of the code using the devtools R package.

# Install devtools, if you haven't already.
install.packages("devtools")

library(devtools)
install_github("michbur/signalHsmm")

After installation GUI can be accessed locally:

library(signalHsmm)
gui_signalHsmm()

All signalHsmm functionalities can be also invoked in batch mode, for example:

run_signalHsmm(benchmark_dat[1:10])
