[Insight-users] image reader update error

[Ashish Singh]

Thanks for replying Dan. Yes that's what it is,
reader->SetFileName(fileNames[fni]).
The fname was a typo in my previous message,sorry for that. It doesn't work
with
reader->SetFileName(fileNames[fni])

The exact error message is a pop up box, titled Microsft Visual C++ debug
Library. It reads-
---------
Debug Assertion Failed!
Program:...
File: C:\program Files(x86)\Microsft Visual Studio 8\VC\include\vector
Line: 756

Expression: vector subscript out of range

For information on how your program can cause assertion failure, see the
Visual C++ documentation on asserts.

abort-retry-ignore

Do you know what is going wrong here?

Thanks,
Ashish
