+# Dynamo
+
+## Installation
+
+Installation was only partially automated in the build script. Currently only the 'prep' step is implemented. Future versions will add more commands to the build script.
+
+Installation should be done on merlin with an -adm account
+
+1. Add new version to `files/variants`
+2. Add google drive download link to `$V/config`.
+3. Run `build <version>`
+4. module load dynamo/$V
+5. Compile stand-alone: `dynamo_setup_linux.sh`
+6. Compile MPI: `source dynamo_setup_cluster.sh mpic++ dynamo_activate_linux_shipped_MCR.sh`
+7. Compile Cuda:
+
+    cd $DYNAMO_ROOT/cuda
+    make clean
+    ./config.sh
+    grep CUDA_ROOT makefile
+    make all
+    make extended
+

+Dynamo is a software environment for subtomogram averaging of cryo-EM data.  In
+a full workflow, you would organize tomograms in catalogues, use them to pick
+particles and create alignment and classification projects to be run on
+different computing environments.
