mscred ccdproc won't see my

[kanaan]

I am running
PyRAF 1.8.2 Copyright (c) 2002 AURA
Python 2.6.5 Copyright (c) 2001-2010 Python Software Foundation.
NOAO/IRAFNET PC-IRAF Revision 2.14.1 Mon Sep 15 10:12:05 MST 2008
This is the RELEASED version of IRAF V2.14 supporting PC systems.

when trying to run ccdproc / mscred:

ERROR (1, "No zero level calibration image found")

but, I do have a Zero file:

--> ls -l Zero.fits
-rw-r--r-- 1 kanaan kanaan 7125120 2010-11-30 16:09 Zero.fits
--> imhead Zero.fits
Zero.fits: FXF: must specify which FITS extension (Zero.fits)
--> imhead Zero.fits[0]
Zero.fits[0][0][short]: Bias

here is my parameter list for ccdproc/mscred:

--> lpar ccdproc
images = "@objlist" List of Mosaic CCD images to process
(output = "") List of output processed images
(bpmasks = "") List of output bad pixel masks
(ccdtype = "") CCD image type to process
(noproc = no) List processing steps only?
(xtalkcor = no) Apply crosstalk correction?
(fixpix = no) Apply bad pixel mask correction?
(overscan = no) Apply overscan strip correction?
(trim = no) Trim the image?
(zerocor = yes) Apply zero level correction?
(darkcor = no) Apply dark count correction?
(flatcor = no) Apply flat field correction?
(sflatcor = no) Apply sky flat field correction?
(split = no) Use split images during processing?
(merge = no) Merge amplifiers from same CCD?
(xtalkfile = "") Crosstalk file
(fixfile = "") List of bad pixel masks
(saturation = "INDEF") Saturated pixel threshold
(sgrow = 0) Saturated pixel grow radius
(bleed = "INDEF") Bleed pixel threshold
(btrail = 20) Bleed trail minimum length
(bgrow = 0) Bleed pixel grow radius
(biassec = "") Overscan strip image section
(trimsec = "") Trim data section
(zero = "Zero.fits") List of zero level calibration images
(dark = "") List of dark count calibration images
(flat = "") List of flat field images
(sflat = "") List of secondary flat field images
(minreplace = 1.0) Minimum flat field value
(interactive = no) Fit overscan interactively?
(function = "minmax") Fitting function
(order = 1) Number of polynomial terms or spline pieces
(sample = "*") Sample points to fit
(naverage = 1) Number of sample points to combine
(niterate = 1) Number of rejection iterations
(low_reject = 3.0) Low sigma rejection factor
(high_reject = 3.0) High sigma rejection factor
(grow = 0.0) Rejection growing radius
(fd = )
(fd2 = )
(mode = "al")

any clews? Sounds like something stupid, but I can't find what it is...

thanks,

Antonio

I was having the same problem too, so we must both be crazy/stupid. I've upgraded to IRAF 2.15.1 and mscred 5.0.2 but now have hit another bug so I don't know if that fixes the problem or not.
