Hi,

I get an error massage when I try to run some files in the directory examples.

Traceback (most recent call last): File "demo_skyview.py", line 60, in im2 = ax2[header_radio].imshow_affine(d, File "/home/tuahlamov/program/python/epd_free-7.2-2-rh5-x86/lib/python2.7/site-packages/pywcsgrid2/axes_wcs.py", line 1310, in getitem ax = ParasiteAxesSky(self, key) File "/home/tuahlamov/program/python/epd_free-7.2-2-rh5-x86/lib/python2.7/site-packages/pywcsgrid2/axes_wcs.py", line 989, in init tr = WcsSky2SkyTransform(src_coord, dest_coord) + \ File "/home/tuahlamov/program/python/epd_free-7.2-2-rh5-x86/lib/python2.7/site-packages/pywcsgrid2/wcs_transforms.py", line 189, in init self.coord_conv_func = coord_conv(src_coord, dest_coord) File "/home/tuahlamov/program/python/epd_free-7.2-2-rh5-x86/lib/python2.7/site-packages/pywcsgrid2/wcs_transforms.py", line 10, in coord_conv return sky2sky(src, dest) File "/home/tuahlamov/program/python/epd_free-7.2-2-rh5-x86/lib/python2.7/site-packages/pywcsgrid2/wcs_helper.py", line 59, in init src = coord_system[src.lower()] AttributeError: 'Header' object has no attribute 'lower'

Could I get your help?

Can you tell me which version of pywcsgrid2 you are using, and versions of other tools that pywcsgrid2 depends on.

import pywcs
print pywcs.__version__
import pyfits
print pyfits.__version__

Currently, I'm testing pywcsgrid2 with the environment listed in the following link. And I cannot reproduce the error you're reporting.

In [2]: pywcs.version Out[2]: '1.11-0.0.dev1022'

In [46]: pyfits.version Out[46]: '3.1-0.0.dev1022'

I tried to re-install pyfits.3.0.7, but it still doesn't work.

I apologize for my late response. pywcsgrid2 still does not work?

I just tried

pywcs==1.11-4.8.2 pywcsgrid2==0.1b2 pyfits==3.0.8 matplotlib==1.0.1

and it worked okay. I also tried

pywcs==1.11-4.8.2 pywcsgrid2==1.0-git (current master) pyfits==3.0.8 matplotlib==1.2.x (current master)

it also worked okay. Note that the version of pywcs and pyfits are what are current in the pypi server.

Because of the changes in pyfits & pywcs, it may not work for some versions. But I could not test this with all the combinations. Can you upgrade your installation of pywcs and pyfits and see if it solves the problem?

Thank u for ur reply, and I have figured it out.

I failed to make it work because I installed the 'astrolib' package which include pywcs and pyfits. It works well now with pyfits and pywcs installed respectively. At 2012-07-17 00:43:15,"Jae-Joon Lee" reply@reply.github.com wrote:
