how to Construct a Newick tree file from five large fasta files

Question

[nikhil]

can anyone help me with a step wise process for this, thank you

1. What have you tried?
2. You need to tell us WAY more about what data you have (how large is large? is each of the 5 a single sequence?)
3. Newick is just a file type. It tells you very little about the content of the tree, so what kind of tree do you want? NJ? ML?
   1. This is not a "Forum" type post, I have changed it for you this time.

I have 30 MB of each five fasta files verticilium species genomes , actually I'm working on augustus for genome annotation of those species , for running annoation in augutus cgp( comparative gene prediction) i need a newick file of those 5 species. Thank you

You haven't said what type of tree you need (newick is not a type of tree, just a data representation/format).

You could try something like mashtree since your data is so large a sketch might be better/easier, though with only 5 genomes I'm not sure how good the tree will be.

I need a phylogenetic tree for those 5 genomes

[Joe]

Yes, I know - but that doesn't answer the question.

What kind of phylogenetic tree?
