ALMA Data Handling Workshop

9-12 February 2016 – Area della Ricerca Bologna, Italy

The Italian node of the European ALMA Regional Center is pleased to announce a 4-day ALMA data analysis workshop, with the aim to assist users in learning how to (re)process ALMA data, from raw data to the production of calibrated images and data analysis.

The program will include lectures introducing the key concepts in the calibration and imaging of interferometric data and hands-on sessions that will demonstrate their application in the Common Astronomy Software Applications (CASA) package.

Participants will be requested to work on their own laptops. Details on CASA versions and data downloads will be communicated later to the registered participants.

The workshop is open to researchers, post-docs and students interested in working with ALMA data, either their own or taken from the archive. Novice users are welcome!

Accessing the ARC cluster

  • The folders used for the school will be available up to Feb 29th. To access the ARC cluster do ssh -X . To work remotely on the school datasets (in scuola/) we suggest creating two individual folders and copying all the files you need into them.
  • If you want to copy files from the cluster to your own machine, you need to type: scp .
  • If you want to use the ARC cluster to work on your ALMA data please contact and visit: for instructions.
  • To fix the CASA viewer problem in the spectral line panel, Linux users can copy this file into their .config/NRAO/CASA/Spectral Profiler.conf file.

Instructions for the hands-on sessions

During the hands-on sessions, we will try to use the hardware and software facilities available at the ARC node. However, we request the participants to:

  • bring their own laptop to access via ssh to the ARC cluster (linux or mac)
  • download from the website the file for the software APSYNSIM 1.2b in the version suited for your own operative system and verify that it is working properly
  • download the latest version of CASA (4.5.0) from the website install it on the laptop and verify that it is working properly. Older versions of CASA might not be suitable for the data that we will be using and will be slower than the last one, so please upgrade to this version if you have already a CASA version installed. Notice that it will be necessary only as a backup in case of malfunctioning of the ARC cluster or of the web links. You will soon receive further instructions on the download of the data that will be used as a backup.

Please contact us for any problem.
