Whenever I try to use MCSIMAGE I get this: " ERROR: No input image data found in 'input.fits' ". My input files are a mosaic images and I can open them normally using MSCDISPLAY. Following http://www.noao.edu/noao/noaodeep/ReductionOpt/frames.html, I use the following parameters:

PACKAGE = mscred
TASK = mscimage

input = List of input mosaic exposures
output = List of output images
(format = image) Output format (image|mef)
(pixmask= yes) Create pixel mask?
(verbose= yes) Verbose output

# Output WCS parameters

(wcssource = image) Output WCS source (image|parameters)
(reference = ) Reference image
(ra = INDEF) RA of tangent point (hours)
(dec = INDEF) DEC of tangent point (degrees)
(scale = INDEF) Scale (arcsec/pixel)
(rotation = INDEF) Rotation of DEC from N to E (degrees)

# Resampling parmeters

(blank = 0.) Blank value
(interpolant= sinc17) Interpolant for data
(minterpolant= linear) Interpolant for mask
(boundary= constant) Boundary extension
(constant= 0.) Constant boundary extension value
(fluxcon= no) Preserve flux per unit area?
(ntrim = 8) Edge trim in each extension
(nxblock= INDEF) X dimension of working block size in pixels
(nyblock= INDEF) Y dimension of working block size in pixels

# Geometric mapping parameters

(interac= no) Fit mapping interactively?
(nx = 10) Number of x grid points
(ny = 20) Number of y grid points
(fitgeom= general) Fitting geometry
(xxorder= 4) Order of x fit in x
(xyorder= 4) Order of x fit in y
(xxterms= half) X fit cross terms type
(yxorder= 4) Order of y fit in x
(yyorder= 4) Order of y fit in y
(yxterms= half) Y fit cross terms type
(fd_in = )
(fd_out = )
(fd_ext = )
(fd_coor= )
(mode = ql)

Do you know what the issue is?

Thanks!

Try doing a

cl\$this->_split2($m[0]) reset use_new_imt = no

before running the task to bypass what could be a bug in the image template code. Otherwise, do you have write permission on the image? Even though the task may not update an image, it may sometimes be opened read-write.

After doing the 'reset use_new_imt = no' command I still get this error:

ERROR: Cannot open image (tmp4801md)
"nyblock=nyblk, verbose=no)"
line 233: mscsrc$mscimage.cl
called as: `mscimage ()'

I have full read/write permission.

That usually fixes it. The task is failing in GEOTRAN when trying to open the mask file "tmp4801md.pl" that was created by the MSCGMASK task. Does this file exist in your directory after it crashes? If you do an "lpar mscgmask", is the 'empty' parameter true (indicating no masks could be created)? Do you actually have the BPM mask files listed in the 'BPM' header keyword for the image? Is the path (if any) correct?
