COMPILING FROM SOURCE
release from and uncompress itDownload the latest
# Get latest STAR source from releases wget https://github.com/alexdobin/STAR/archive/2.7.10b.tar.gz tar -xzf 2.7.10b.tar.gz cd STAR-2.7.10b # Alternatively, get STAR source using git git clone https://github.com/alexdobin/STAR.git
Compile under Linux
# Compile cd STAR/source make STAR
For processors that do not support AVX extensions, specify the target SIMD architecture, e.g.
make STAR CXXFLAGS_SIMD=sse
Compile under Mac OS X
# 1. Install brew (http://brew.sh/) # 2. Install gcc with brew: $ brew install gcc # 3. Build STAR: # run 'make' in the source directory # note that the path to c++ executable has to be adjusted to its current version $cd source $make STARforMacStatic CXX=/usr/local/Cellar/gcc/8.2.0/bin/g++-8 # 4. Make it availible through the terminal $cp STAR /usr/local/bin
All platforms - non-standard gcc
If g++ compiler (true g++, not Clang sym-link) is not on the path, you will need to tell
make where to find it:
cd source make STARforMacStatic CXX=/path/to/gcc
If employing STAR only on a single machine or a homogeneously setup cluster, you may aim at helping the compiler to optimize in way that is tailored to your platform. The flags LDFLAGSextra and CXXFLAGSextra are appended to the default optimizations specified in source/Makefile.
# platform-specific optimization for gcc/g++ make CXXFLAGSextra=-march=native # together with link-time optimization make LDFLAGSextra=-flto CXXFLAGSextra="-flto -march=native"
STAR can be installed on FreeBSD via the FreeBSD ports system. To install via the binary package, simply run:
pkg install star
This release was tested with the default parameters for human and mouse genomes. Mammal genomes require at least 16GB of RAM, ideally 32GB. Please contact the author for a list of recommended parameters for much larger or much smaller genomes.
