Support tools for the hands-on training sessions
  • Singularity container with the CTF DataEditor tool and the SAMsrc MEG tools running under CentOS 6.9
Singularity container megcore.img download
  • Text editors available within the container for editing shell scripts: vim, nano, gedit
Usage: singularity shell --bind /data:/mnt/data megcore.img
where the /data file system holds your CTF data set and mounts under /mnt/data inside the container
(your /home directory and the /tmp file systems are automatically visible inside the container)
  • Working on the NIH HPC systems
Data are still available in /data/classes/meg, along with all necessary scripts
Modules are now available for SAM (samsrcv3) and CTF (ctf).
To begin:
Copy the data from /data/classes/meg
Use the initialization script to configure your environment:
$ . init_course.sh
