How filter node inside view block by even nid (or odd nid) I have a view 2 blocks where I show some images and I'm trying to show the images with an even nid in the 1st block and the images with odd nid in the 2nd block

Do you guys have any idea if it's possible? and how?
@IsmaH answer is on the right track (use Regex for filtering nid). The problem in his answer is that this filter uses mySQL Regular Expressions - this is why his proposed regex is not working. 

This worked for me:
^.*[13579]$

or this for even numbers: ^.*[02468]$

Notice: no slashes at the beginning and end of the expression.
