I've been getting the following error message when reducing SOAR data with imextensions
\$this->_split2($m[0]) imextensions *.fits
ERROR: No write permission on file (String_File)
Here are the following things I've tried / determined:
- I also experienced the error when running CCDPROC but only when it was dependent on another image ... so to subtract a bias (Zero.fits) or a flat (Flat.fits). Trimming and overscan subtraction worked fine, for example. My guess is that this issue is tied into the one above.
- I got the same error message when running on the command line or within a procedure.
- I only encounter the error message when attempting to reduce SOAR data (data from 3 other telescopes / instrument combinations works fine).
- This doesn't appear to be a "one night only" issue -- I've tried the reductions with 3 nights of data ... same error message.
- I checked my /tmp folder and it isn't full
- Now for a strange one ... if I run imext on a small number of files (~30), it will work fine. But, if I run it on a night's set of data (~500 images), it will die.
Based on the above information, I'm thinking it might be an issue with the SOAR image headers (though, I can't explain why it only works on a small number of images but not a lot ...). I'll put an image header at the bottom.
I was able to reproduce this issue on two machines ... but both are MacOSX 10.10.2 running NOAO/IRAF PC-IRAF Revision 2.16.1 EXPORT Mon Oct 14 21:40:13 MST 2013.
Any ideas?
Example image header:
PHP Formatted Code 0114 .2015BM510img .fits [1548,1548,1][ushort ]: 2015BM510
No bad pixels , min=0., max=0. (old )

Try doing:
cl\$this->_split2($m[0]) reset use_new_imt = no
before running the task. This will disable the new image template code and use the old version, I think you may be seeing a known string buffer overflow with large lists. If it works, you can make the change permanent by editing the hlib$zzsetenv.def file.
