Thank Matthew, I had been testing the indexes and they looked fine.
In fact:<br>
<br>
Rank-0, is_0: [0 1 2] [633 634 635]<br>
Rank-0, is_1 [636 637 638] [729 730 731]<br>
Rank-1, is_0: [732 733 734] [1368 1369 1370]<br>
Rank-1, is_1 [1371 1372 1373] [1464 1465 1466]<br>
<br>
where is_1 should be much smaller, and it is indeed the case. <br>
<br>
Thanks!<br>
