Dear All,
Do we need to keep all log files. It has taken 23G of my HD.
Thanks,

From what I've been told some of the 454 PE can be quite finicky and also
require a good deal of luck. I think that in your case, the sequencing provider
is very probably not at fault.

Some of those duplicate reads are easily spotable by eye in an assembly:
identical start and stop, identical sequence, all in the same direection. You'd
need to have a really high coverage even in 454 to get these things in normal
sequencing.

I'll send you the link for a download by PM.

Uh ... you'd be actually the second person to do that. Though the first one who
did didn't do it because of MIRA :-)

Cannot be the real problem, at least I would not think so.
Best,
