Hi,

It isn't possible to tell what is happening from what you have described. I suggest that you do a couple of things.

1. test that the file really exists by using

IDL> ok = FILE_TEST('theNameOfYourFileWithCompletePathIncludingDriveLe tter')
IDL> print,ok

2. check the read permissions on the file. I can't recall how to do that on windows, but within IDL you can use something like

IDL > info = FILE_INFO('theNameOfYourFileWithCompletePathIncludingDriveLe tter')
IDL > help, info,/str

3. if those don't help you resolve the issue, then the next thing is to paste the entire unedited error message you see into your next message to the group.

Cheers,
Ben
