Description

The ability to predict B cell epitopes from antigen sequences is critical for biomedical research and many clinical applications. However, despite substantial efforts over the past 20 years, the performance of even the best B cell epitope prediction software is still modest. Based on the idea of T-B reciprocity, BepiTBR is a B cell epitope prediction model that demonstrates improved performance by incorporating prediction of nearby CD4+ T cell epitopes close to the B cell epitopes.

Full Protein Mode identifies potential B cell epitopes from a full antigen protein sequence, this mode requires the antigen protein sequence to be input directly


Usage

Example command using provided example files:

(replace paths with appropriate paths according to user's particular installation)


raku BepiTBR.raku \
--full0=$(cat examples/test_data_BepiTBR_full/example_full.txt) \
--length=15 \
--bepipred2=bp2/bin/activate \
--bepipred1=/home/exampleUser/bp1/bepipred-1.0/bepipred \
--LBEEP=/home/exampleUser/LBEEP/ \
--MixMHC2pred=/home/exampleUser/MixMHC2pred/MixMHC2pred_unix \
--netMHCIIpan=NA \
--dir=/home/exampleUser/BepiTBR/examples/test_output_BepiTBR \
--thread=8
                    

Arguments

Name Explanation
full0 protein sequence
length length of the B cell epitopes to scan in a moving window. Recommended length: 15
bepipred2 the conda environment activation file for BepiPred 2.0
bepipred1 path to the BepiPred 1.0 executable
LBEEP path to the LBEEP directory
MixMHC2pred path to the MixMHC2pred executable
netMHCIIpan path to the NetMHCIIpan 3.2 executable
dir output directory
thread number of CPU thread to use; system dependent

Details

1. Required tools (BepiPred 1.0, BepiPred 2.0, LBEEP 1.0, NetMHCIIpan 3.2, MixMHC2pred) must be installed before executing model. For more details about installation and other dependencies, please visit our GitHub.

2. For BepiPred 2.0, this tool requires an isolated python virtual environment (python 2.7). After installation, It is recommended to move the bp2 env directory into the BepiTBR main directory.

3. It is recommended to set netMHCIIpan to NA for better run speed.
