XPA Error #12

Closed ghost closed 9 years ago

ghost commented 9 years ago

When I attempt to send a .fits image file to pyds9 I get the following error message:

ValueError: XPA$ERROR undefined command for this xpa (DS9:ds9 7f000101:33016)

I should note that I am using the latest version of Ubuntu (if that helps). This error only occurs when I try to set a .fits image to ds9. I can still successfully send an array to ds9 (via set_np2arr()), and it displays perfectly.

Any suggestions?

The error indicates that you are not passing the "fits" argument in the param list. I believe this xpa access point requires two args: "fits" in the param list and the actual fits data in the data arg. If this is not the problem, please tell me the args you are passing.
