Plugin to use motioncorr programs within the Scipion framework
Project description
This plugin allows to use motioncor2 program within the Scipion framework.
Motioncor2 is a GPU-accelerated program for correction of electron beam-induced sample motion. It is developed by Shawn Zheng.

Installation
You will need to use 3.0 version of Scipion to be able to run these protocols. To install the plugin, you have two options:
Stable version
scipion installp -p scipion-em-motioncorr
Developer’s version
download repository
git clone https://github.com/scipion-em/scipion-em-motioncorr.git
install
scipion installp -p path_to_scipion-em-motioncorr --devel
Motioncor2 binaries will be installed automatically with the plugin, but you can also link an existing installation. Default installation path assumed is software/em/motioncor2-1.3.1, if you want to change it, set MOTIONCOR2_HOME in scipion.conf file to the folder where the Motioncor2 is installed. Depending on your CUDA version you might want to change the default binary from MotionCor2_v1.3.1-Cuda92 to a different one by explicitly setting MOTIONCOR2 variable. If you need to use CUDA different from the one used during Scipion installation (defined by CUDA_LIB), you can add MOTIONCOR2_CUDA_LIB variable to the config file. Various binaries can be downloaded from the official UCSF website.
To check the installation, simply run the following Scipion test:
scipion test motioncorr.tests.test_protocols_motioncor2.TestMotioncor2AlignMovies
Supported versions
1.2.3, 1.2.6, 1.3.0, 1.3.1
Protocols
movie alignment
