Functional analysis of Prokaryotes using Gene Set Enrichment Analysis on Transcriptome (RNA-Seq) or Proteome data.
     Gene Set Enrichment Analysis (GSEA) is a method to identify classes of genes or proteins that are over-represented in a set of genes or proteins, respectively. Two data sets are needed to perform a GSEA; 1) A list/set of genes or proteins derived from a transcriptomics or proteomics analysis, 2) A database of functional classes.
     For all complete bacterial genomes of RefSeq and Genbank (>20.000) we (re-)constructed nine functional Classes; GO, InterPro, KEGG, COG, PFAM, SMART, Superfamily, KEYWORDS and OPERONS. GSEA-Pro support 4 types of input: 1) a single list of locus-tags, 2) a single list with values, 3) multiple experiments and 4) clusters. Use this powerpoint TUTORIAL to understand the four input options and how to interpretate the results. Some examples can be selected below.
Both RefSeq and Genbank annotations are supported. Optionally use Genome2D for conversion between Genbank (old_locus-tags) and RefSeq locus-tags

For annotating and Classifying your own genomes you can use the FACoP webserver (or stand-alone)
[ ..]

Select Genome: Start typing parts of the genome name until the selection list is less than 15 genomes. If one genome is in the list, the genome will be selected automatically. e.g. to find Bacillus subtilis 168, just type 2 keywords such as 168 subt and select your genome from the list

Over-represented classIDs and its significance in each experiment/cluster
The values given per experiment; 1) Score [0-9], 2) Hits / Class Size, 3) p-value.
Light to dark blue coloring represents low to high score [based one (Hits/ClassSize) * -log2(p-value)], respectivily
Columns LC and HM contain links to a graphical representation of the original data of the genes/proteins. Note; only shown in multiple experiment analyses
