@subutai Thank you! Yep, now i found an affirmation in the .hpp file, is supposted to work as a circular buffer. (Though it must be rarely used, if ever, as it couldn't have been working before..)

Btw, thinking about it...vectorCount() would be a number of elements, like a dimension ||x||, then the indices are 0..||x||-1, so should be `(NTA_Size)vectorFile_.vectorCount() -1`, right ?
