Yes, It must has the three required columns, and the 9 additional optional
columns must be the same order as the it defined. If you missed any of
them, just insert an empty one, except strand column, which can only
accept '1' '+' '-1' '-' and '*'.

You can download the develop version to accept a file name as inputs,
otherwise, you must feed the function an object of data.frame.

Yours sincerely,
