Error message with PyRaf wregister command

[VASIMR]

Hi,

I am having problems calling the PyRaf wregister command from a python script. I have a list of images that I want to apply the command to, when I do so to individual image sets in the list, I receive this error:

[sontag]

Hi Vasimr,

I don't see a reply here, but I am guessing that is because this was sent to the wrong forum. If the command works perfectly in the IRAF cl, but it has problems in PyRAF, then it is most likely a PyRAF issue, not an IRAF issue. Sorry for the wait, I would have guessed someone following these forums would have directed you to STScI by now.

Nonetheless, we should be able to help you. This sounds like a (hopefully simple) issue passing arguments to wregister. Note that since wreg takes standard IRAF parameters, you cannot pass it a Python list as an argument.

If for example ListC is something like "['file-a', file-'b', 'file-c']", to send that information to wreg, you will want to first change it to a text file like "@listc" which contains those three filenames in it. If wreg was a Python task, it would much more likely understand being sent a Python list as an argument.

If that doesn't fix this for you, please create the smallest possible Python script which reproduces the problem, and send your help request to help@stsci.edu.

Cheers,
Chris
