By annotate, you likely mean "align". There are a LOT of options (the linked wikipedia article is not likely to be exhaustive). The best one will likely depend on your goals and available computational resources.

I think he actually might mean annotate, as in finding and calling structural motifs and functional genes.
Since you said a large genome, I'm going to assume eukaryotic. There are a number of software packages that can help you do annotation, but I've never used any of them so I'll let someone else comment on which to try first.
To get started you can always begin ORF calling with Glimmer3 and finding your tRNAs with tRNAscan.
You might also want to try posting this in the Bioinformatics forum as this one is more about handling the instruments and sequencing and not the later processing as much.

Following only applies if you have a "final" sequence file (your original post is not clear on this point) that requires annotation.
If the genome is prokaryotic then you may want to take advantage of the automatic bacterial genome annotation pipeline provided by NCBI: http://www.ncbi.nlm.nih.gov/genomes/static/Pipeline
If this is a eukaryotic genome then this page provides a guide for the process of annotation: http://www.ncbi.nlm.nih.gov/genome/a...n_euk/process/

Originally posted by dpryan View PostCould be, "annotate" is an incredibly overused word in bioinformatics, such that I think many people don't know that it requires an object (i.e., annotate it with what?). It's like asking a molecular biologist how to "measure a protein sample"

Thanks dpryan, mcnelson.phd & genomax for the suggestions.I have the fasta file of a sample obtained from illumina hiseq genome analyser.Want to do complete annotation of the file and should include the number of chromosomes,unplaced regions,coding and non coding etc. How is Nextgene software can it be used to get the complete annotation of the sample file?

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-
