Hello everyone?

when I run the IDL procedure file (IDL file with .pro extention), it is taking almost 24 hours. Now I'm still waiting for the result. Is it normal thing or something wrong in a procedure and files. Actually my files (images)used in procedure file are very huge (column: 12354, row: 4688, Band:7 in each). This procedure file has been written on 3 such huge images. IDL can read these images through procedure file. I'm wondered why it takes so long time to run? and what is the reason? Is it because of files? etc.

Thanks so much you
Best bishes,
Bandrush

I can imagine a poorly written procedure that
requires a lot of paging in and out of memory,
with the images available over a network connection,
taking a long time to process. I wouldn't have
24 hours of patience myself. I would have stopped
it after 20 minutes and had a go with smaller
files to see if that was the problem. :-)

Cheers,

David
