Display and DS9

daisymak wrote on Nov 08, 2006

I got a problem when I try to use DS9 to display images.
I have installed CIAO in my Fedora Core 5 and there is ds9 included in it. So when I have to use ds9, I have to start CIAO first.
Then I installed iraf on the same machine and try to use ds9 as the display device for iraf. However, I got the following error message:
ecl > display crfree.hhh
ERROR: Cannot open device (node!imtool,,512,512)
no matter I open the ds9 or not. Would anyone please offer some help ?

Hi

I run FC4. If you run IRAF, with ds9 installed in your extern directory, with the correct links. I.e you can start ds9 from anywhere. then al you need to do is start-up ds9 before you start iraf. The best method is to call it from your loginuser.cl file.

# Start ds9
!ds9

Hope this helps.

Regards
Pat

If it will not help you, can you show us your login.cl?
Here is my piece of ligin.cl and i not have a problem with DS9:

# Uncomment and edit to change the defaults.
#set    editor          = vi
#set    printer         = lp
#set    pspage          = "letter"
#set    stdimage        = imt800
#set    stdimcur        = stdimage
#set    stdplot         = lw
#set    clobber         = no
#set    filewait        = yes
#set    cmbuflen        = 512000
#set    min_lenuserarea = 64000
set     imtype          = "fits"
set     imextn          = "oif:imh fxf:fits,fit,fts plf:pl qpf:qp stf:hhh,??h"

Good luck!

I have solved the problem
It is due to my $display variable in iraf account.
I have to set permission on iraf account in order to use display
In addition, i have to add this line to the login.cl in order to use ds9 in iraf:
task $ds9 = "foreign"
I don't know why this works, but at least now I can use ds9 to display images now
