epar rfits
inp bias01.fits
out bias01r.fits

Error message is;
Unable to open parameter file `uparm$daorfits.par'.
ERROR: T_RFITS: Undefined output file name

I'm confused because the RFITS task doesn't have an "inp" or "out" parameter, but the error is definitely coming from the RFITS task. I also don't know why you'd be running RFITS on a FITS image, can you provide more details?

ok Mike, sory

PACKAGE = dataio
TASK = rfits

fits_fil= bias01.fits FITS data source
file_lis= File/extensions list
iraf_fil= bias01r.fits IRAF filename
(make_im= yes) Create an IRAF image?
(long_he= no) Print FITS header cards?
(short_h= yes) Print short header?
(datatyp= ushort) IRAF data type
(blank = 0.) Blank value
(scale = yes) Scale the data?
(oldiraf= no) Use old IRAF name in place of iraf_file?
(offset = 0) Tape file offset
(mode = ql)
:go
And return me:
Unable to open parameter file `uparm$daorfits.par'.
ERROR: T_RFITS: Undefined output file name

I try to rfits, because when I run any task, like imstatis, return me read error.
" Error reading image"

I'm still confused (it's late here), why are you trying to run RFITS on the 'bias01.fits' image when you can use it as-is? You shouldn't be seeking that error unless the 'iraf_file' param is an empty string.

An 'Error reading image' could be a permissions problem or a corrupted FITS file. Are you sure this is a valid image?

Hi Mike,

when you tell "could be a permissions problem", I controlled that I'm not login as su!:oops: So, I try to login as su and problem is solved :P
Im so sorry for taking your time for a simple situation.
Thank you very much.

Type "ls -al" in a terminal to see the file permissions (first column) and "man chmod" to see how to change them so you can work with the files as a normal user. Working as su routinely is a bad idea. It could be the files or the directory itself (.) that needs permissions changing.

James.
