I successfully installed IRAF 2.16 and got problems with the mscred package.
I can run:
Code:
mscred> ccdlist b0212

and I get:
Code:
b0212[im1][1036,2032][ushort][][1][]:SYM6712
b0212[im2][1036,2032][ushort][][2][]:SYM6712

with successful "setinstr" (as in v. 2.15, it worked fine), I run:
Code:
ccdproc b0212 overs+ trim+ merge-

and I get:
Code:
ERROR: Cannot open file (b0212)
  "imcopy (input//"[0]", outname, verbose=no)"
     line 288: mscsrc$ccdproc.cl
     called as: `ccdproc (images=b0212, overscan=yes, trim=yes, merge=no)'

Thank you for any advice.

Two questions: 1) Which architecture is this? And b) if you run the IMCOPY command by itself does it work, e.g.

Code:

imcopy ("b0212[0]", "foo.fits", verbose=no)


do you see the same error?

The V2.16 REPO is full but I haven't yet had time to verify that all the packages were relinked yet.

I use the 32-bit linux architecture installed from "iraf-linux.tar.gz".
When I run:
Code:
mscred> imcopy ("b0212[0]", "foo.fits", verbose=no)

I get:
Code:
Cannot open file (b0212)

so the problem remains. But I have an image "vbias" created with the v. 2.15 with "ccdproc ... merge+" and I can "imcopy" it without any problem. So I am in trouble only with MEF files.

It seems to want the ".fits" extension explicitly, I'm looking at it .....

When I put:
Code:
imcopy ("b0212.fits", "foo.fits", verbose=no)

I get:
Code:
ERROR: FXF: must specify which FITS extension (b0212.fits)

and the code:
Code:
mscred> imcopy ("b0212.fits[0]", "foo.fits", verbose=no)

gives the "foo.fits" but this is an image header inside, the same as:
Code:
imhead b0212.fits[0] lo+

The quick workaround is to do

Code:

cl> reset use_new_imt = no
cl> flpr 0                     (zero, not oh)


to defeat the new image expansion code and get back the old behavior, but otherwise your last report is what I would expect from v215 as well. Note you can also change the default setting of 'use_vo' in the hlib$zzsetenv.def file

Yes, the "quick workaround" works well and the code:
Code:
ccdproc b0212 overs+ trim+ merge+

works without any problem. Thank you so far.

The bug has been fixed and the distribution files were updated with the patch. I was planning to wait a few days to see what else is reported before building a proper patch update, for now I hope you won't mind downloading the v216 installation file and unpacking it once more. Thanks for the report.

Unpacked new "iraf-linux.tar.gz" and I get:
Code:
mscred> ccdlist b
b[im1][1036,2032][ushort][][1][]:SYM6712
b[im2][1036,2032][ushort][][2][]:SYM6712
mscred> ccdproc b
b[im1]: Mar 25 13:20 Trim is [9:1016,9:2024]
b[im1]: Mar 25 13:20 Overscan is [1020:1035,9:2024], mean 1798.776
b[im2]: Mar 25 13:20 Trim is [9:1016,9:2024]
b[im2]: Mar 25 13:20 Overscan is [1020:1035,9:2024], mean 1798.086
ERROR: Cannot open file (tmp$ccdproc4264eP)
  "sigscale=0.1, pclip=-0.5, grow=0., verbose=no)"
     line 417: mscsrc$ccdproc.cl
     called as: `ccdproc (images=b)'
mscred> ccdlist tmp$ccdproc4264eP
tmp$ccdproc4264eP[im1][1008,2016][real][object][1][][OT]:SYM6712
tmp$ccdproc4264eP[im2][1008,2016][real][object][2][][OT]:SYM6712

So I make:
Code:
mscred> reset use_new_imt = no
mscred> ccdproc b
b[im1]: Mar 25 13:25 Trim is [9:1016,9:2024]
b[im1]: Mar 25 13:25 Overscan is [1020:1035,9:2024], mean 1798.776
b[im2]: Mar 25 13:25 Trim is [9:1016,9:2024]
b[im2]: Mar 25 13:25 Overscan is [1020:1035,9:2024], mean 1798.086
b: Merge amplifiers

And it worked. Still problems.

Could I ask you to please download the system once more? If its the problem I think it is then it should be fixed, otherwise I need to get some data so I can reproduce the problem. Thanks.

I downoladed today a new 32bin linux version, installed it, and the problem remains. I also tried download the example image into
Code:
anonymous@iraf.noao.edu/pub

but it was not possible, because I do not have sufficient permission to do it.[/code]

Hi,

I used some dual-amp Mosaic data and tried to reproduce a problem with the latest V2.16. So could you please put an problem image in the ftp pub area and let me know. Also the parameter listing from "lpar mscred ccdproc" and any thing else you think might be appropriate, such as if you have a personalized instrument file.

Thanks,
Frank Valdes

I was not able to ftp it, so I put the data on my server and wrote a private message to you on the iraf.net and an e-mail to the "Contat Us" how to download the problematic image. Thank you,
rj

Thanks for the data and the detailed log, I was able to reproduce the problem and found that aside from the earlier problem in the template expansion, the MSCRED package was accidently relinked with a pre-release version of the system containing a second bug. These have both now been fixed and verified and I was able to run your data with no problem without having to use the workaround.

You'll need to re-install both IRAF and MSCRED. I've built the IRAF patch but not the update script yet so simply get the new distribution file once again (sorry for the repeat installs). To update MSCRED (and all other packages), just do

Code:

% cd $iraf/extern
% make update


Thanks again for your report, and your patience.

I dowloaded the file "iraf.lnux.x86.tar.gz" from a link of:
Code:
http://iraf.noao.edu/

and it did not work - the situation was the same. So I opened:
Code:
ftp://iraf.noao.edu/iraf/v216/PCIX/

and found there "iraf.lnux.x86.tar.gz" (191660 KB, 03/23/2012, 01:25:00 AM) and "iraf.lnux.x86.gz" (195880 KB, 03/28/2012, 08:04:00 PM). I dowloaded the second one, made the installation and I was able to get the correct result. Thank you.

The problem is with PyRAF:
