Good afternoon, I just did a mapping assembly of the results of a de novo assembly. It's an E. coli strain with 40x 454 and 70X Illumina. After I did the de novo assembly, I mapped it against K12 and now I am going to BLAST the non-K12 contigs to see what I have. I took the caf file and did: $ convert_project -f caf -t fasta -t caf -x 500 -y 30 PROJ_out.caf PROJ_out_LargeContigs When I look at the results (ls -1 *.unpadded.fasta) so as not to list the padded results and the qual files, I get: PROJ_LargeContigs_AllStrains.unpadded.fasta PROJ_LargeContigs_ReferenceStrain.unpadded.fasta PROJ_LargeContigs_default.unpadded.fasta I understand what the ReferenceStrain is - one contig was a HUGE hint :) I also know that the other two files have a mapping to the backbone strain as an entry. What else is different between them. (I did do a Google search and read the manual, promise). Thanks John -- You have received this mail because you are subscribed to the mira_talk mailing list.
