Can not produce Spatial Component Analysis Eigenvalue text

[AnthonyGreenish]

Each time I try to produce an Eigenvalue text file when doing a PCA on a 4 band file, I either get an error message or the program crashes. What am I doing wrong? Thanks for your answers.

What is the error?

What is the path and filename to the output *.txt or *.asc file?

The error is 000864 (Output data file: The input is not within the defined domain. ERROR 000814: Invalid file type). The text file I am proposing to use is  "D:\GIS\Default.gdb\Principal4.TXT". Actually, I have tried all kinds of file names and locations without any luck. All I have managed to do is crash the program.
