pdcn
protein function prediction using protein domain co-occurrence network (pdcn - ranked as one of the best methods in CAFA1 competition
Test Environment
Red Hat Enterprise Linux Server release 6.4 (Santiago)
Installation Steps
(A) Download and Unzip profun source package
Create a working directory called 'pdcn' where all scripts, programs and databases will reside:
Download the pdcn code:
cd ~/
git clone https://github.com/multicom-toolbox/pdcn.git
cd pdcn
(B) Download programs
cd programs
wget ftp://ftp.ncbi.nlm.nih.gov/blast/executables/legacy.NOTSUPPORTED/2.2.26/blast-2.2.26-x64-linux.tar.gz
tar -zxvf blast-2.2.26-x64-linux.tar.gz
(C) Download database
mkdir database
cd database
mkdir swiss_prot
cd swiss_prot
wget ftp://ftp.uniprot.org/pub/databases/uniprot/knowledgebase/uniprot_sprot.fasta.gz
wget ftp://ftp.uniprot.org/pub/databases/uniprot/knowledgebase/uniprot_sprot.dat.gz
gzip -d uniprot_sprot.dat.gz
gzip -d uniprot_sprot.fasta.gz
../../programs/blast-2.2.26/bin/formatdb -p T -i uniprot_sprot.fasta
wget http://purl.obolibrary.org/obo/go/go-basic.obo
(D) Configuration
perl configure.pl
(E) Test
mkdir -p ./test/2SN3-A/sequence ./test/2SN3-A/Blast_output
(1) Run blast
perl scripts/exe_swiss.pl ./test/2SN3-A.fasta ./test/2SN3-A/sequence ./test/2SN3-A/Blast_output
(2) Run prediction
perl scripts/get_swiss.pl ./test/2SN3-A.fasta ./test/2SN3-A/2SN3-A_function.txt ./test/2SN3-A/Blast_output
perl scripts/get_function.pl ./test/2SN3-A/2SN3-A_function.txt ./database/go-basic.obo ./test/2SN3-A/2SN3-A_functionnew.txt
output
>2SN3-A
