So, what is your question?

[asl]

Well, the log reads:

Too much reads aligned with negative insert size. Is the library orientation set properly?

So, you need to check your input data, whether you specified it properly, whether the library preparation was ok, etc. It has nothing to do with programming.

I think the input data should be fine since it is a tutorial data for beginners...... am I wrong ?
what my next step should be ( in this case) ?

[asl]

Given the warning, the data is probably not fine. Or you're specifying it improperly.
