I see your point. Short answer: no, there is currently no way to reduce that 
output. Most of it is indeed pretty boring for users who just want their stuff 
assembled, but in case there is a problem or some kind of unexpected behaviour, 
it helps me to at least get an idea of what is going on. This is somewhat vital 
for larger assemblies where I cannot ask people to constantly rerun things for 
2 weeks on their computers.

I'm sorry, but for projects like yours, you will have to live with logs of >= 
1GiB. But then again, what's a GiB disk space anyway.

In case you wonder: there is a way to make the log even more verbose, I'd guess 
around 200 to 300x larger, but it involves recompiling and I do have the 
feeling that this is quite opposite of what you wanted :-)

Hrm ... I think that this could be remedied, perhaps have MIRA report just the 
first 1000 names which are too long. Or something like that. Could ease the 
pressure a bit. I'm puttinhg that on my TODO (but no promises).


I couldn't help but quickly scan through the rest of the log, noticing a couple 
of things:

1) you're doing an assembly with unpaired 454 and unpaired Illumina, is that 
correct?
2) where did you get those ~200bp Illuminas from? By the look of the 
statistics, they must be pretty good in quality ... clipped only some 4% of the 
total bases and that's not worse than the 100bp reads I have seen so far.

B.

PS: and would you like to test drive the current development version with your 
data set to comment on whether you think it's better or worse?
