This is the most recent version of 3DFSC, by Philip Baldwin, Yong Zi Tan, and Dmitry Lyumkis.
GPU code and Conda environment by Carl Negro.
3DFSC Program Suite requires Miniconda 3 to run, and UCSF Chimera to visualize the outputs.
Important: this version of the software has been modified to work with updated dependencies (October 2023). I have tested it with cudatoolkit 11.8
conda create -y -n fsc3D-3.0 "python<3.12" cudatoolkit=11.8conda activate fsc3D-3.0pip install numpy numba scipy click h5py scikit-image matplotlib mrcfilegit clone https://github.com/azazellochg/fsc3D fsc3D-3.0
To view the 3DFSC parameters, access the help info like ThreeDFSC/ThreeDFSC_Start.py -h.
3DFSC now has GPU support through Numba for faster execution (typically ~10x faster than the CPU implementation). This requires that CUDA is installed correctly. See http://www.nvidia.com/Download/index.aspx.
To make use of a GPU, simply append the --gpu flag as a parameter to ThreeDFSC_Start.py script.
You can select which GPU to use for processing with the --gpu_id flag. E.g. --gpu_id=2 to run 3DFSC on the GPU with index number 2. The program currently only allows a single GPU to be used at once; this may change in future versions.
To see a list of available GPU's and corresponding indices, run nvidia-smi. If you are unable to run nvidia-smi, check to make sure you have CUDA installed correctly.
Note that GPU memory is limited, so that processing jobs with large box sizes will fail.
