Hi!
I just installed iraf and encountered a strange problem. I just wanted to quickly combine some fits files, and typed "imcombine *.fits output.fits"
the strange thing: "Warning: Cannot open file(machine!/home/username/work/1.fits"
of course, machine is the name I gave the machine when I installed ubuntu 10.04 (64bit) and username is my default user.
I never saw this and have no Idea whats wrong... do you know it by chance? :)
thx.

Could it be due to the file size of images? one has around 2.5 gb.

That would do it. You'll need the IRAF v2.15 system in order to deal with files >2GB in size and other 64-bit issues. Prior to that, IRAF is a 32-bit system and so the filesize would be a problem. Similarly, a "64-bit filesystem" would have inodes that exceed 32-bits and so the files where the inode exceeds 32-bit wouldn't be visible/readable to IRAF. Another problem might be the machine name, e.g. "Arp's Machine" is a problem in the node!path syntax due to the space in the name.
In any case, you'll need v2.15 to at least deal with the large files.
