Hopefully the scripts contained in this documentation are (a) useful and (b) work. They were however developed with CASA still a work in progress, and so scripts may break as commands, arguments, and keywords change. We developed this script extractor to allow us to easily extract scripts from these pages and run them. Feel free to try it!

Note: the intention is to extract CASA scripts for testing; commands which are to be run on the command line outside of CASA, or within other software packages, will not be extracted.

How to Get the Script Extractor

Download the script extraction code. 

# in bash
ftp ftp.cv.nrao.edu
# log in anonymously with e-mail as password
cd NRAO-staff/jgallimo
get extractCASAscript.py

Wget may be even simpler if you have it installed. 

# in bash
wget ftp://ftp.cv.nrao.edu:/NRAO-staff/jgallimo/extractCASAscript.py

How to Use the Script Extractor

Make your newly acquired python script executable. 

# in bash
chmod u+x extractCASAscript.py

To run it, issue the python script name and give the URL as the argument. For example: 

# in bash
extractCASAscript.py http://casaguides.nrao.edu/index.php?title=Calibrating_a_VLA_5_GHz_continuum_survey


This command will automatically generate a script called "CalibratingaVLA5GHzcontinuumsurvey.py"
