prPred is a tool to identify the plant resistance proteins (R proteins)
prPred is an open-source Python-based toolkit, which operates depending on the Python environment (Python Version 3.0 or above). Before running prPred, user should make sure all the following packages are installed in their Python environment: subprocess, datetime, os, shutil, pandas,numpy, Biopython,sklearn,optparse
To obtain HMMER releases, please visit http://hmmer.org/. We also provide HMMER zipped folders for download in prPred
<prPred need to make sure that the HMMER is in the environment variable>
sudo apt-get install hmmer
Download and build the source code release(optional)
wget http://eddylab.org/software/hmmer/hmmer.tar.gz
tar zxf hmmer.tar.gz
cd hmmer-3.3.2
./configure --prefix /your/install/path
make
make check
make install
vim ~/.bashrc

'''
Error - could not read provided fasta sequences
Modify line 24 in phobius.pl
my $DECODEANHMM = "$PHOBIUS_DIR/decodeanhmm.64bit"
'''
Add phobius into environment variables (~/.bashrc)
export PATH=$PATH:/xxxx/xxxx/xxxxx/tmp/tmpbKioAY/phobius
To obtain Pfam database,please download from ftp://ftp.ebi.ac.uk/pub/databases/Pfam/current_release/Pfam-A.hmm.gz
mkdir Pfam
cd Pfam
wget ftp://ftp.ebi.ac.uk/pub/databases/Pfam/current_release/Pfam-A.hmm.gz
gunzip Pfam-A.hmm.gz
hmmpress Pfam-A.hmm
'''
After hmmpress, we will get four files: Pfam-A.hmm.h3f，Pfam-A.hmm.h3i，Pfam-A.hmm.h3m，Pfam-A.hmm.h3p
'''
Add PFAMDB (Pfam-A.hmm.h3f，Pfam-A.hmm.h3i，Pfam-A.hmm.h3m，Pfam-A.hmm.h3p) into environment variables
vim ~/.bashrc**
export PFAMDB=/xxxx/xxxx/xxxx/Pfam
To obtain iFeature, please download from https://github.com/Superzchen/iFeature/.
Add iFeature into environment variables (~/.bashrc)
export PATH=$PATH:/xxxx/xxxx/xxxxx/iFeature
###prPred
git clone [email protected]:Wangys-prog/prPred.git
Add prPred into into environment variables
(./prPred/dist/prPred)
export PATH=$PATH:/xxxx/xxxx/xxxx/prPred/dist/prPred
prPred -h
$ -i inputfile in FASTA format
$ -o output folder
prPred -i /xxxx/xxxx/test/test.fasta -o result
or Using absolute path to invoke prPred.py (/xxxx/xxxx/prPred/prPred.py)
python xxxx/xxxx/prPred/prPred.py -i /xxxx/xxxx/test/test.fasta -o /xxxx/xxxxx/result
