How to use naivebayes on ordinary data not on text files?

I hava an ordinary data file containing labels and  feature vectors.
How can I use naivebayes to classify it?
The example on the official website is used with text files. Can it be used
on ordinary files?

I wonder if *trainnb* can be directly used on data files only if the format
of data file is ok.

For example, one line of data file is like this:

1 3 4 5 6 7

first column is label. Other columns construct the feature vector

Ordinary files?
What type of file you are using?
