-----------------------------------------------------------------------
The ASTRA Toolbox is a MATLAB and Python toolbox of high-performance GPU
primitives for 2D and 3D tomography.
We support 2D parallel and fan beam geometries, and 3D parallel and cone beam.
All of them have highly flexible source/detector positioning.
A large number of 2D and 3D algorithms are available, including FBP, SIRT,
SART, CGLS.
The basic forward and backward projection operations are GPU-accelerated, and
directly callable from MATLAB and Python to enable building new algorithms.
Documentation / samples:
-------------------------
See the MATLAB and Python code samples in samples/ and on
http://www.astra-toolbox.com/ .
Installation instructions:
---------------------------
Windows, binary:
-----------------
Add the mex and tools subdirectories to your matlab path and the Python module
to your Python path.
Linux, from source:
--------------------
For Matlab:
Requirements: g++, boost, CUDA (5.5 or higher), Matlab (R2012a or higher)
cd build/linux
./autogen.sh # when building a git version
./configure --with-cuda=/usr/local/cuda \
--with-matlab=/usr/local/MATLAB/R2012a \
--prefix=$HOME/astra \
--with-install-type=module
make
make install
Add $HOME/astra/matlab and its subdirectories (tools, mex) to your matlab path.
If you want to build the Octave interface instead of the Matlab interface,
specify --enable-octave instead of --with-matlab=... . The Octave files
will be installed into $HOME/astra/octave .
NB: Each matlab version only supports a specific range of g++ versions.
Despite this, if you have a newer g++ and if you get errors related to missing
GLIBCXX_3.4.xx symbols, it is often possible to work around this requirement
by deleting the version of libstdc++ supplied by matlab in
MATLAB_PATH/bin/glnx86 or MATLAB_PATH/bin/glnxa64 (at your own risk),
or setting LD_PRELOAD=/usr/lib64/libstdc++.so.6 (or similar) when starting
matlab.
For Python:
Requirements: g++, boost, CUDA (5.5 or higher), Python (2.7 or 3.x)
cd build/linux
./autogen.sh # when building a git version
./configure --with-cuda=/usr/local/cuda \
--with-python \
--with-install-type=module
make
make install
This will install Astra into your current Python environment.
Windows, from source using Visual Studio 2015:
-----------------------------------------------
Requirements: Visual Studio 2015 (full or community), boost (recent), CUDA 8.0,
Matlab (R2012a or higher) and/or WinPython 2.7/3.x.
Using the Visual Studio IDE:
Set the environment variable MATLAB_ROOT to your matlab install location.
Copy boost headers to lib\include\boost, and boost libraries to bin\x64.
Open astra_vc14.sln in Visual Studio.
Select the appropriate solution configuration (typically Release_CUDA|x64).
Build the solution.
Install by copying AstraCuda64.dll and all .mexw64 files from
bin\x64\Release_CUDA and the entire matlab/tools directory to a directory
to be added to your matlab path.
Using .bat scripts in build\msvc:
Edit build_env.bat and set up the correct directories.
Run build_setup.bat to automatically copy the boost headers and libraries.
For matlab: Run build_matlab.bat. The .dll and .mexw64 files will be in bin\x64\Release_Cuda.
For python 2.7/3.5: Run build_python27.bat or build_python35.bat. Astra will be directly installed into site-packages.
