Why is IRIS looking for @1.pic.pic?

[cybereye]

I've been trying to use IRIS to do some preprocessing and all is fine until the program goes to divide the flat into the light image.

The program fails with an error saying that it can't find the file @1.pic.pic. From what I can see the file that it is after is @1.pic so I'm unsure why it wants the other file. However, if I try to rename my file from @1.pic to @1.pic.pic it still says that it can't find the file.

Has anyone seen, and solved, this problem before? :help:

Cheers,
Mario

Some thoughts.
Iris doesn't like dots in the file name.
You also dont need to tell it the file extension as it will add them.
Make sure the file path is correct in the options.
An example.
I have a list of files like these
orion1.pic
orion2.pic
orion3.pic
orion4.pic
and I want to subtract a dark frame from them called dark.pic
The command would be
sub2 orion dark a 0 4
This would subtract the dark frame, add an offset of 0 and create output files called
a1.pic
a2.pic
a3.pic
a4.pic

If I used a command that has intermidiate files to create like the preprocessing dialogue Iris creates files with @ in their name.
When you enter the file name in the dialogue box you need to not add the number or file extension ie the "1.pic" otherwise it will look for a file called orion1.pic1.pic that doesn't exist and give you an error.

Terry,

These files were automatically created by IRIS and then needed in the same run. I'll check that my working directory is OK.

Thanks for the ideas,
Mario
