How to use the basic UNIX commands pwd, ls, and cd to navigate through your files from a command-line prompt. Consed will be run from the command line, so knowing these is a prerequisite.

How to use 454's program Newbler (aka GS De Novo Assembler) to assemble phage genomes that have been sequenced by 454, Ion Torrent, or Illumina technologies. Newbler is installed on the 2013 SEA-PHAGES virtual machine.
Selecting a Subset of Reads From an SFF or FASTQ File

This video tutorial demonstrates how to take a subset of sequencing reads from an .sff file (454 or Ion Torrent output) or a .fastq file (Illumina output). This can be useful when assembling phage genomes, since NextGen sequencing technologies often return too many reads to get a good assembly for a single phage genome.

This video tutorial demonstrates how to add reads from an .sff or .fastq file to an existing consed assembly project. This can be useful if only a subset of the reads were used in the initial assembly.
