Viewing Non-Standard Genomes

Is there a way to look at a non-standard genome in a genomics browser like IGV or IGB? I usually use IGV so that would be by preference for a genome browser, but given that I currently have no way of looking at my genome, I would settle for anything.

Basically, I know how many chromosomes by genome has and how big the chromosomes are. I just need something in which to view a wig file for my genome.

EDIT: Yes, I do have a fasta file of the genome.

Also, I don't care that much about the format: wig, bedgraph, bigwig, bigbedgraph. It's just that my data happens to be in wig so I guess i kind of wrote that without thinking. I know how to convert if I need to.

Can you provide a bit more information? Do you have a FASTA file for your genome? Is the genome submitted to GenBank/ENA/DDBJ?

IGV will accept a new genome. Create a new .genome file using the menu option All you need is the fasta file. Also you can load annotation from local files (e.g. gff)

This is just to expand on the comments by Alastair Kerr and deanna.church and combine them into an answer.

Every genome browser offers the option to import a custom genome. Usually located under names as such as "Import Genome". You just need a FASTA file that will then be indexed and saved in a format that the browser can load quickly. If your genome is large this may take a while to run.

The web apollo team has a really impressive browser. It suports wig format. There is some overhead setting it up, but once that is done it is pretty smooth. Size shouldn't be a problem.

Seconding the suggestion of WebApollo. It's built on the same framework as JBrowse (http://jbrowse.org; AJAX-y version of the popular genome browser GBrowse), it's very slick and fast, and is great for collaborative manual annotation of genomes. You can get WebApollo, JBrowse, GBrowse, plus other GMOD tools (Chado DB, Tripal DB interface) on GMOD in the Cloud, which is a virtual machine hosted in the Amazon cloud - everything is installed and ready to go; you just load your data. See http://gmod.org/wiki/Cloud for more on GMOD in the Cloud.

NCBI also has a client side tool called genome workbench. If the assembly is in our Assembly DB you can just search and load it. If it is a private assembly, you can load FASTA files (or AGPs if they point to accession.versions).

You can load annotation files as well as doing other analysis (alignments, etc).
