I want to annotate the fungal genome which I got from 454. For that I have predicted the genes using AUGUTUS tool (i have now a output file in gff format) using command-

augustus --species="Homo sapiens" --UTR=on 454AllContigs.fna > output.gff

Now i have gff file, now how can i use this file for annotation. Should i use other tools for annotation ?

Stajich's lab ( does fungal genome annotation and they use a pipeline that includes PASA ( I've never tried it though, but it seems to work quite well for them.

I've been using MAKER for annotating my fungal species (using RNA-Seq data) and it's worked really well so far. You can feed your gff model directly into it and it'll annotate the genome using a bootstrap gene prediction re-training method.

i have installed the MAKER tool, now which command should i use as a for fungal genome annotation ?

i am not able to find any workflow available for MAKER (fungal genome annotaion) as we can see in MOTHUR/QIIME.


So, can you tell me the commands which i can use for fungal genome annotation, as you have done work on MAKER.

Here's a great tutorial on how to get it running:

And here's further explanation of the config files to control what's happening under the hood:

That should give you enough information to get you up and running, and to tweak it to your needs.

i tried to follow MAKER, i got an error, i used command (NOTE: i have only fungal genome in fasta format)-

Judging from what I see in your terminal output, it's as if you defined the genome, organism_type, etc. as variables in your shell, rather than in the maker_opts.ctl file. The maker_opts.ctl file is what you're looking to modify because it points Maker to the input files/settings.
