deepredeff is a package to predict effector protein given amino acid sequences. This tool can be used to predict effectors from three different taxa, which are oomycete, fungi, and bacteria.
You can install the released version of deepredeff from
CRAN with:
install.packages("deepredeff")And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("ruthkr/deepredeff")The deepredeff package uses TensorFlow. If you already
have TensorFlow 2.0.0 or later in your system, then you can specify the
environment where TensorFlow is installed using
reticulate::use_condaenv(). Otherwise, you can install
TensorFlow, by using the install_tensorflow() function as
follows:
library(deepredeff)
install_tensorflow()Note that this only needs to be run once, the first
time you use deepredeff.
To use deepredeff, you can read the documentation on the
following topics:
This is a basic example which shows you how to predict effector sequences if you have a FASTA file:
# Load the package
library(deepredeff)
# Define the fasta path from the sample data
bacteria_fasta_path <- system.file(
"extdata/example", "bacteria_sample.fasta",
package = "deepredeff"
)
# Predict the effector candidate using bacteria model
pred_result <- predict_effector(
input = bacteria_fasta_path,
taxon = "bacteria"
)
#> Loaded models successfully!
#> Model used for taxon bacteria: ensemble_weighted.# View results

After getting the prediction results, you can plot the probability distribution of the results as follows:
plot(pred_result)
