HiI am experimenting problems reducing Gmos IFU data using IRAF package with MacOSX Lion 10.7.4.
I installed IRAF using scisoft package (MAcOSIntel 2012.6.1). The IRAF version is V2.16, and the gemini package is I perform a simple task using gfreduce to add the MDF mask, trim and substract a bias:
gfreduce FILE fl_extract- fl_gsappwave- fl_wavtran- fl_skysub-It seems that the gprepare part runs fine, but when it begins the gireduce, an error occurs:===============================================================================================
===============================================================================================
GPREPARE exit status: good.

===============================================================================================
===============================================================================================I tried to display other files coming from previous reduction with another Mac but the prb remains.
The gFILE generated can be vizualize (with gdispl) and reduce with gfreduce, in an other machine without prbs. So the gprepare task in
my machine is working fine.Can someone can help me ?Thanks

Hello,The Gemini IRAF package is not yet compatible with IRAF v2.16. Please see http://www.gemini.edu/sciops/data-and-results/processing-software for more details.Many thanks,Emma
