+This is a template for asking questions and reporting bugs. Please fill in as much information as you can.
+
+**Describe your problem**

+Please write a clear description of what the problem is.
+
+**Environment:**
+ - OS: [e.g. Ubuntu 16.04 LTS]
+ - MPI runtime: [e.g. OpenMPI 2.0.1]
+ - RELION version [e.g. RELION-3.1-devel-commit-6ba935 (please see the title bar of the GUI)] 
+ - Memory: [e.g. 128 GB]
+ - GPU: [e.g. GTX 1080Ti]
+
+**Dataset:**
+ - Box size: [e.g. 256 px]
+ - Pixel size: [e.g. 0.9 Å/px]
+ - Number of particles: [e.g. 150,000]
+ - Description: [e.g. A tetrameric protein of about 400 kDa in total]
+
+**Job options:**
+ - Type of job: [e.g. Refine3D]
+ - Number of MPI processes: [e.g. 4]
+ - Number of threads: [e.g. 6]
+ - Full command (see `note.txt` in the job directory):
+   ```
