Hi Everyone,I've been beating my head against this problem for a couple of days now, without being able to solve it myself. Maybe someone here can point me in the right direction.I am attempting to run a cl script that someone gave me. It works for them and it works for them when they log into the same machine I am using. When I try to run the cl script (imal2.cl) myself WITHOUT a pre-existing .par file, I get the following message:cl> imal2
ERROR: Required parameter `reference' not defined.When I use the .par file from the person who gave me the script, I get the following message instead:cl> imal2

ERROR: cannot read parameter file `scripts$imal2.par'When I look at the parameter file, all of the parameters are enclosed by " ". However, judging from the error messages, IRAF is apparently looking for parameters to be enclosed by ` '. Does anyone know why this would happen?Cheers,Brandon Tingley

It is hard to comment without seeing either the script or the parameter file, could you please post these?If your uparm directory has a corrupted version of the parameters then you could try unlearning the task to start fresh, this might explain why you're having problems but your friend isn't.-Mike

OK, I'll post them.First the script:procedure imal2 (images, coords, reference)begin
bool shifts_found = no string l_images, l_coords, l_reference
string workimage
string imgfile, imcefile,modefile, shiftfile, trimsect, tmp, junk
string ajunk,bjunk,cjunk
int n
real xshift, yshift
struct line
print("A") imgfile = mktemp ("tmp$iag_tmp.")
l_images = images
l_reference = reference
l_coords = coords
print("B") sections (l_images, option="fullname", > imgfile)
imglist = imgfile
while (fscan (imglist,workimage) != EOF) {
imcefile = mktemp ("tmp$iac_tmp.")
shiftfile = mktemp ("tmp$ias_tmp.")
#don't shift previous shifted frames
print("C")
imgets(workimage,"IMSHIFT", >& "dev$null")
if (imgets.value != '0') {
print(workimage," already shifted by ",imgets.value)
goto endloop
} if (autoback) {
modefile = mktemp ("tmp$iam_tmp.")
imstat.fields = "mode"
imstat.format = no
imstat(workimage,>& modefile) tmplist = modefile
while(fscan(tmplist,background) == 1) {
print("\n",workimage," background set to ",background) }
delete (modefile, ver-, >& "dev$null") } print("D") imcentroid (workimage, coords=l_coords, reference=l_reference,
shifts=shifts,
boxsize=boxsize, bigbox=bigbox, negative=negative,
background=background, lower=lower, upper=upper,
niterate=niterate, tolerance=tolerance, verbose=verbose, >& imcefile
) if (verbose)
type (imcefile) # read the shifts
shifts_found = no
tmplist = imcefile
while (fscan (tmplist, line) != EOF) {
if (substr(line,1,7) == '#Shifts') {
shifts_found = yes
break
}
} if (shifts_found) {}
else{
print(workimage," no shift was calculated !")
print("Continue with next frame? (yes/no)")
n=scan(tmp)
if(stridx('yY',tmp) == 0) error (1, "aborted on request")
}
if (! shiftimages)
goto endloop
if (shifts_found) {
while (fscan (tmplist, junk, xshift, junk, yshift, junk) == 5){
print (xshift, " ", yshift, >& shiftfile)
}
if (copyorg) {
print("copying original image")
imcopy(workimage,"org_"//workimage,verbose=yes)
} print(workimage," being shifted by ",str(xshift)//" "//str(yshift)) imshift (workimage, workimage, shifts_file=shiftfile,
interp_type="nearest", boundary_type="nearest",

o,verify=no,update=yes,show=no)
} tmplist = ""endloop:
delete (imcefile, ver-, >& "dev$null")
delete (shiftfile, ver-, >& "dev$null")
} imglist = ""
delete (imgfile, ver-, >& "dev$null")end

...and the parameters file:images,s,a,,,,"List of images"

imglist,*s,h

I don't see anything obviously wrong with either the parameter file or the script. Did unlearning the task change anything? What happens if you create a new login.cl/uparm in some other directory and declare the task from there? I'm trying to work out whether this is a problem with your account, rarely there are problems with e.g. a file not containing an EOF (sometimes happens with emacs), but since things seem to work for me and your friend, it sounds like something in your setup is the issue.-Mike

Thanks for looking it over.It's a brand new installation, this is the first thing I tried to do at my new job. All the other scripts I was given for this task work fine.Tried unlearning before I posted here :-/Could it possibly be something with the set-up of my computer account, rather than an iraf setting?

OK, my collaborator re-wrote a big chunk of it and now it works.Problem avoided, if not resolved
