MIDAS

**** V8 Released ****

Code for reduction of High Energy Diffraction Microscopy (HEDM) data developed at Advanced Photon Source.

In case of problems, contatct Hemant Sharma.

SGInfo library used to calculate HKLs.

Some misorientation functions are taken from the ODFPF package from Cornell.

Downloads NLOPT, LIBTIFF, FFTW, HDF5, BLOSC, BLOSC-2, ZLIB, LIBZIP for compilation of N(F)F-HEDM codes.

Installation and Compilation Instructions:

Download the source code from GitHub.

git clone https://github.com/marinerhemant/MIDAS.git

Change to the MIDAS directory.

cd MIDAS

To compile on LINUX, skip to step 5.

To compile on MACOS, please use the following steps:

1. Install Homebrew if not already installed. If you don't have Homebrew installed, you can install it by running the following command in your terminal:

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

   Follow the on-screen instructions to complete the installation. Also place the Homebrew binary in your PATH by adding the following line to your ~/.zshrc file:

   echo 'eval $(/opt/homebrew/bin/brew shellenv)'  >> ~/.zshrc

   Then, reload your shell configuration:

   source ~/.zshrc

2. Install the required libraries using Homebrew:

   brew install llvm libomp gcc cmake jemalloc
   

3. Set the environment variables for the compiler (copy paste the following commands in your terminal):

    echo 'export PATH="/opt/homebrew/opt/llvm/bin:$PATH"' >> ~/.zshrc
    echo 'export LDFLAGS="-L/opt/homebrew/opt/llvm/lib $LDFLAGS"' >> ~/.zshrc
    echo 'export CPPFLAGS="-I/opt/homebrew/opt/llvm/include $CPPFLAGS"' >> ~/.zshrc
    echo 'export LDFLAGS="-L/opt/homebrew/opt/libomp/lib $LDFLAGS"' >> ~/.zshrc
    echo 'export CPPFLAGS="-I/opt/homebrew/opt/libomp/include $CPPFLAGS"' >> ~/.zshrc
    echo 'CC=/opt/homebrew/opt/gcc/bin/gcc-15' >> ~/.zshrc
    echo 'export CC' >> ~/.zshrc
    echo 'CXX=/opt/homebrew/opt/gcc/bin/g++-15' >> ~/.zshrc
    echo 'export CXX' >> ~/.zshrc
   

4. Reload your shell configuration:

   source ~/.zshrc
   

5. Run the build script:

   ./build.sh
   

6. Install the Python requirements:

   conda env create -f environment.yml
   

7. Activate the conda environment:

   conda activate midas_env
