Hello Yuxuan,
Oh, we're all hard-working people, here! ;)
Is this the error you're getting (from the celldetect error messages page,
http://asc.harvard.edu/ciao/errors/celldetect.html)?
-------------------------
"ERROR: Failed to open a DM image in dataset %s. DM Error: %s."
CAUSE:
dsDMOPENIMAGEERR - Datamodel couldn't open an image.
FIX:
See DM error. Filename is probably wrong. Remember that a file specified with
Datamodel "[]" syntax must be quoted. If the dataset is null ("image in
dataset ."), you specified a blank filename somewhere.
-------------------------
It may be you made a small error in the filename. Also, when using a source
detection tool on an event file, you need to specify the events block, e.g.
"infile='evt.fits[events]'".
Alternatively, I know that some people have had success by dividing their
image into smaller chunks (say, 1k x 1k), and running the detect tool on each
chunk. Then the output source files can be merged (after trimming out the edge
effects).
Sorry if this isn't much help, but as you noted, it's late!
best of luck,
casey
