![]() You can download it from David Agard’s page and follow his installation instructions. If you want, you can still use the (GPU-accelerated) UCSF program. Relion implements its own (CPU-only) implementation of the UCSF motioncor2 algorithm for whole-frame micrograph movie-alignment. Most Linux distributions have packages called libtiff-dev or libtiff-devel. RELION needs libtiff version >= 4.0 to deal with TIFF files and EER movies. FFT libraries:ĭepending on your CPU, Intel MKL FFT or AMD optimised FFTW might run faster. This can be installed automatically (see below). Īlternatively, you may also use (the closed-source) gctf by Kai Zhang, which may be downloaded from Kai’s website. Instead, relion provides a wrapper to Alexis Rohou and Niko Grigorieff’s ctffind 4. Note that CUDA toolkits support only a limited range of C compilers.Īlso note that a newer CUDA toolkit requires a newer GPU driver.Ĭarefully read the release note and make sure you have a compatible set of GPU driver, C compiler and CUDA toolkit. In order to compile relion with GPU-acceleration support, you’ll need to install cuda. If you have a modern GPU from nvidia with compute capability 3.5+, you can accelerate many jobs considerably. If you don’t have an MPI installation already on your system, we recommend installing OpenMPI. Your system will need MPI runtime (most flavours will do). Note that relion depends on and uses several external programs and libraries. The sections below explain how to download and install relion on your computer. it is completely free, open-source software for both academia and industry. Relion is distributed under a GPLv2 license, i.e.
