Hi, I am trying to align some RNAseq data using STAR. I am new to analysing RNAseq data and know only basic scripting. I'm having a bit of trouble installing (and understanding the installation instructions) STAR on a Mac OS X platform. Are there specific instructions (scripts) anyone could point me to? Any help will be much appreciated.
An easy way to install STAR would be to use Homebrew, in case you don't already have it. It not only have Unix utilities you can download but there a plethora of science tools also available. Once you have Homebrew installed, installing STAR can be as easy as
brew install homebrew/science/rna-star
I hope that proves to lower the barrier to at least playing around with STAR.
Otherwise, I feel that their instructions were pretty clear.
# Get latest STAR source from releases wget https://github.com/alexdobin/STAR/archive/STAR_2.4.2a.tar.gz tar -xzf STAR_2.4.2a.tar.gz cd STAR_2.4.2a # Build STAR cd source make STARforMacStatic
Once you have downloaded and unzipped the package. There is already a precompiled executable which can be found in:
So, either explicitly state the path to the executable or export the path (if you are using bash in MacOSX):
That should work.
