Default

Hi all,

I was wondering why the default for spantiles is set to false. If a read for instance has coordinates (1000,1000) and the dupedist is set to 2500, (see sketch attached), there's a possible overlap with 3 other tiles. So even if it's not a NextSeq, but a HiSeq4000 for instance, there are no tile-edge duplicates, however there's still a possibility that optical duplicates end up on neighboring tiles (or even further). Can anyone elucidate on this?

Thanks in advance!

Attachment: The dot represents the "original read", the circle represents the distance of 2500 around the "original read". Rectangles represent tiles.
