genome assembly -- 2

I am looking for someone to help me with my de novo genome assembly project. I I just need a complete guide on how to do this, because I have been stuck. Apparently I need a FASTA file and without it I cannot answer the questions I am given. I have rerun the job four times already but there is no FASTA file. I am willing to provide you with all the information needed, including what I have written this far.
