This software implements a template-free particle fusion algorithm based on an all-to-all registration, which provides robustness against individual mis-registrations and underlabeling. The method does not assume any prior knowledge about the structure to be reconstructed (template-free) and directly works on localization data not pixelated images.
The main code is written in MATLAB and some of the compute-intensive kernels have been written in CUDA and C++.
Use the following commands to build the necessary libraries for this software:
cmake .
make
make installCMake locates the code's dependencies and generates a Makefile. Make compiles the mex files and necessary shared libraries. Make install copies the mex files to the right directory for use in Matlab, it does not require priviledges to run.
Make sure you have all dependencies downloaded and installed. In particular make sure that your CUDA version and MS Visual Studio version are compatible. Use the following commands to build the necessary libraries for this software:
mkdir build
cd build
cmake -G "Visual Studio 14 2015 Win64" -DCUB_INCLUDE_DIR="C:\path_to_your_cub_dir\cub" ..
cd ..
python fix_msbuild_files.py
Then open MS Visual Studio, for example by double clicking on ALL_BUILD.vcxproj and build all the targets. It could be that you manually need to build the targets expdist and gausstransform before building the other targets.
Then, copy all the .mexw64 files from build/Debug/ to the MATLAB/all2all directory.
If you do not have a CUDA capable GPU you could install the software without GPU acceleration. Do note that the code will be orders of magnitude slower. Use the following commands to install the CPU-only version:
cmake -DUSE_GPU=OFF .
make
make installAn example of how to use the code on experimental and simulated data is shown
in the MATLAB script demo_all2all.m.
CMake is used as the build system for compiling the code. Here is a quick way to install the latest version of CMake locally without the need for root access:
- Run the following from your terminal and also add it to your ~/.bashrc file for future usage.
export PATH=$HOME/bin:$PATH
export LD_LIBRARY_PATH=$HOME/lib/:$LD_LIBRARY_PATH- Head over to the CMake downloads page and get the latest “Unix/Linux Source” *.tar.gz file.
- Run the following command sequentially (this can take a few minutes !):
tar -xf cmake*.tar.gz
cd cmake*
./configure --prefix=$HOME
make
make install- You should now have the new installation of cmake ready. Check the version by:
cmake --versionThe main code is written in Matlab, it's not possible to use the software without it. The DIPImage toolbox for MATLAB is required, please see http://www.diplib.org for installation instructions.
The GPU code requires a CUDA-capable GPU as well as the CUDA toolkit to be installed. Please see Nvidia's website for installation fo the CUDA toolkit (https://developer.nvidia.com/cuda-downloads).
The GPU code currently has one dependency, which is the CUB library. You can
download it from: https://nvlabs.github.io/cub/index.html The easiest way to
install CUB is to add the directory where you unpack CUB to your $CPATH
environment variable.
This code has been developed for a Linux enviroment. We have yet to test it on OSX and Windows, but the CMake build system should support compilation on these platforms. If you run into issues using the software on Windows or Mac please create an issue on GitHub or contact the authors.
The GPU code has only one external dependency, which is the CUB library. cmake will try to find and locate the CUB library on your system. If that fails it will attempt to download the library directly. If that fails, you could install the library manually.
You can download CUB from: https://nvlabs.github.io/cub/index.html. The easiest
way to install CUB is to add the top-level directory of where you've
unpacked the CUB source codes to your $CPATH environment variable. For
example, if you've unzipped the CUB sources into a directory called
/home/username/cub-version.number, you can use
export CPATH=$CPATH:/home/username/cub-version.number/: to install CUB. In this way the
nvcc compiler is able to find the CUB headers.
Note that the mex files for the GPU code will be installed into the MATLAB/all2all directory.
Once the mex files for the GPU code have been produced,
the MATLAB code will prefer to use the GPU functions instead of the CPU
functions. If you have no GPU available but did compile the mex files for
the GPU code, you will get errors and MATLAB will exit. To disable the use
of the GPU code remove the mex files from the MATLAB/all2all directory and reinstall using cmake -DUSE_GPU=OFF ..

The testing and tuning scripts for the GPU code have been written in Python, using Kernel Tuner. This section provides information on how to setup a development environment. Note that these steps are only needed if you are interested in modifying the CUDA and C++ codes.
The tests for the GPU code and several of the C functions are written in Python, to run these a Python 3 installation is required. The easiest way to get this is using Miniconda.
On Linux systems one could type the following commands to download and install Python 3 using Miniconda:
wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh
All the required Python packages can be installed using the following command, before you run it make sure that you have CUDA installed:
pip install -r requirements.txt
The tests can be run using nose, for example by typing the following in
the top-level or test directory:
nosetests -v
