Newbler assembly - excluding specific reads?

[JonB]

Hi,

I have sequenced genomic DNA from a eukaryote and have ran a newbler assembly of the sff file from the 454 lab. Some of the contigs are clearly belonging together, but are not assembled into one. This seems to be caused by a few reads that looks like artefacts from the genomic amplification. (These reads are split into two and the two halves match each end of the contig, like a circle.)

I wonder if it is possible to run newbler and to specify that these reads (i have the names) should not be considered?

Thanks!

Jon

Jon,

Yes, you can exclude specific reads from the assembly. Create a text file with the read names you wish to exclude, one name per line, nothing else. When you run newbler use the parameter '-fe <filename>' where filename is the file described above.
