Berkeley IDL Users

IDL is the Interactive Data Language. It has become a popular tool for data analysis and visualization around these parts. This page is here for a few reasons:
  • Berkeleyans have some useful code to contribute to the world.
  • It's nice to have a gateway to the most useful IDL resources on the internet.
  • The UCB Astronomy Department has an IDL Users Mailing List. Pertinent useful information offered to this forum will be collected here.

Setting Up Your IDL Environment

  • I'm running IDL in an xterm. Sometimes my command line becomes so long that it wraps to the next line. When I notice that I typed prnit rather than print, I can't access the line above. What's the deal?
      Your xterm is not set to enable Reverse Wraparound. Type <SHIFT>-<MIDDLE BUTTON> in the xterm and select "Enable Reverse Wraparound" or start your xterm with the -rw flag.
  • Where do all the locally contributed procedures live? I want to use them on my laptop.
      From your sun account:
        > cd /usr/local/rsi/idl
        > tar cf ~/ulib.tar ulib
      Then copy ~/ulib.tar to your laptop's /usr/local/rsi/idl directory. Then on your laptop:
        > cd /usr/local/rsi/idl
        > tar xf ulib.tar
  • When I try to start IDL on my laptop, it says that I don't have a valid host for the license. It was working fine when I was away at XXX. What do I do now?
      Probably, the hostname in the license file is set to what it was at XXX. Edit /usr/local/rsi/license/license.dat. Change the hostname there to match your current hostname (which you can get by typing hostname or uname -n.)
