Hi Bastien,

We are currently running assembly of a 4 mb genome using solexa paired end
100bp lenght & 200bp insert size & file size is 7.2 GB in fastq format.
Below are the call parameters:

/bin/bin/mira --project=b90a --fastq --job=denovo,genome,accurate,solexa
-highlyrepetitive SOLEXA_SETTINGS -GE:tismin=100:tismax=300

The process is stuck at the below spet for a week now:

Searching for possible overlaps:
Localtime: Sat Jan  1 00:46:10 2011
Now running threaded and partitioned skimmer with 208 partitions in 2
threads:
 [0%] ....|.... [10%] ....|.... [20%] ....|.... [30%] ....|.... [40%]
....|.... [50%] ....|.... [60%] ....|.... [70%] ....|.... [80%] ....|....
[90%] ....|.... [100%] 

We checked the log folder and found that the size of the 2 files named
b90a_int_posmatchc_preassembly & b90a_int_posmatchf_preassembly is
constantly increasing. Now both files are 146 GB in size and mira is also
using a swap of 36 gb. 

Should we let this run or stop the assembly?

Regards,
Aayushmaan Bansal
