hello all~
i am trying to use imcombine for several images. i keep getting the following error message:
ecl> imcombine @test1.txt sub1.fits combine=median
PANIC in `/iraf/iraf/bin.redhat/x_images.e': segmentation violation
test1.txt is a list of image segments of the same size located in another folder (i include the folder's location in the file). i can't for the life of me figure out why this isn't working. can you please help me?

Hello,
I don't have an idea why you have this problem. If this is reproducible I could diagnose it if you supply a parameter listing (dpar or lpar) and the data files. You can put the data files either on an ftp site at your end or at iraf.noao.edu/pub. Let me know directly if you do this (valdes@noao.edu).
Yours,
Frank Valdes
Also let me know the version of IRAF.

Please see the lead article on the homepage for information about a critical update just released which may explain the error you are seeing. Please reinstall the binaries (a source update is not required) and let us know whether the problem continues.

yea, i (or rather, my coworker) reinstalled the binaries, but i'm still having the same problem -- only part of the time. my colleagues and i diagnosed that it's not a problem with the formatting of the list file or the image itself.

Hi,
As I noted, there is not much I can do without being able to reproduce the problem. In addition to trying to do it on our systems I am also available, if you wish, for me to login remotely where you have set up things so it is easy to do what you do and get the same result. You can communicate directly with me about diagnosing options at valdes@noao.edu as this forum is not likely to resolve the problem.
Yours,
Frank Valdes
