# NetPathMiner [![Travis-CI Build Status](]( NetPathMiner implements a flexible module-based process flow for network path mining and visualization, which can be fully inte-grated with user-customized functions. It supports construction of various types of genome scale networks from three different pathway file formats, enabling its utility to most common pathway databases. In addition, NetPathMiner provides different visualization techniques to facilitate the analysis of even thousands of output paths. To report bugs and arising issues, please visit ## Installation Instructions ### System Prerequisites NetPathMiner depends on libxml2 and libsbml to process pathway files. Installation or running certain functions MAY fail if these prerequisite libraries are not available. Please read through the following instructions. #### Prerequisites for Unix users (Linux and Mac OS) ##### Installing libxml2 Make sure your system has library libxml2 installed. In Mac OSX 10.6 or later, libxml2 are built in. For Linux users also, this is almost always the case, however, developing headers may be missing. To install libxml2 and the headers: ```Shell sudo apt-get install libxml2 sudo apt-get install libxml2-dev ``` ##### Installing libSBML Installing libSBML for Unix users is optional. However, NetPathMiner will not be able to process SBML files. If you will not use SBML functions, you can skip this part. From the website of libSBML, you can directly download the binaries suitable for your system from ``Download libSBML'' link. You can follow the installation instructions on the website. #### Prerequisites for Windows users If you are installing the package through Bioconductor, you don't have to install external libraries. However, currently the Bioconductor version for Windows doesn't support SBML processing. Alternatively, we have prepared all dependencies in a tar file, downloadable from . Please download the file and place in in the home directory of R (type <code>R RHOME</code> in command prompt to locate it), before installation. Unless you want to use customized libraries, you can skip the rest of this section.To use customized libraries, you have to compile them and provide them to R at the time of installation. This is not a trivial task, please be sure you really need these custom libraries. ##### Installing libxml2 NetPathMiner expects an enviroment variable `LIB_XML` or `LIB_XML2` pointing to directory where libxml2 is installed. This directory should have both the compiled library (DLL file) and the header files. You can download libxml2.dll from among other sources. Please, place it in a `bin` folder under the installation directory. You will need also the header files, which can be obtained from NPM_dependecies.tar file. After extracing it, copy the include directory to the installation directory. Finally, set the `LIB_XML2` variable to point to the installation directory, which should now contain dll files inder `bin` and header files under `include`. ##### Installing libSBML Since libSBML is a C++ libraries, it needs to be compiled using GCC compiler. Unforturantely, there is no binary version for Windows comipled with GCC. To use libSBML, you need to build it from source. First, dowload source package from , extract it. You will need also MinGW or the 64-bit version depending on your system. Add `mingw/bin` to your PATH, by editing eviroment variables. Second, you need CMake . You can follow the instructions at , however, choose "MinGW Makefiles" instead of "Visual Studio 10". After finishing the CMake step, use the MinGW's `make.exe` to compile libSBML. Copy the dependencies you used during the compilation to the `bin` directory. Set the enviroment variable `LIB_SBML` to point the installation directory, which should now contain dll files inder `bin` and header files under `include` ### R Package dependencies NetPathMiner depends on package igraph to represent network objects. Installing igraph is required for the package to work. You will also need devtools package to install directly from github. NetPathMiner suggests package rBiopaxParser to process BioPAX files and RCurl to download annotations from the web. NetPathMiner can still work without installing the suggested packages, but you will not be able to use the aforementioned functionalities. ##### igraph Package igraph is available at CRAN. To install it call: ```r install.packages("igraph") ``` ##### devtools Package devtools is available at CRAN. For Windows, this seems to depend on having Rtools for Windows installed. You can download and install this from: To install R package devtools call: ```r install.packages("devtools") ``` ##### RCurl For Unix users, make sure your Linux has library libcurl installed. Check out: ```Shell locate libcurl locate curl-config ``` If these are not found (usually the developer version is missing), most Linux users will be able to fix this by running: ```Shell sudo apt-get install libcurl4-openssl-dev ``` You will now be able to install R package RCurl. In R console: ```r install.packages("RCurl") ``` If you encounter other problems check out ##### rBiopaxParser Package rBiopaxParser is available on Bioconductor. For installation instructions check out or call: ```r source("") biocLite("rBiopaxParser") ``` to install it right away. ### NetPathMiner Installation If everything went well you will be able to install the NetPathMiner package. #### From Bioconductor: In R console, type: ```r source("") biocLite("NetPathMiner") ``` #### From GitHub using devtools: In R console, type: ```r library(devtools) install_github(repo="NetPathMiner", username="ahmohamed") ```
