Hi,

I have a list of IPI gene IDs.  I want to find out whether there is a
package which can map the gene ontology to these IPIs, and plot the
pie chart to demonstrate the molecular function distributions.

The input is like the following gene IPI IDs:
IPI:IPI00008860.1|SWISS-PROT:Q9BXJ4-1|TREMBL:Q542Y2|ENSEMBL:ENSP00000231338;EN
IPI:IPI00019922.5|SWISS-PROT:Q8N0Y2-1|TREMBL:Q53F81|ENSEMBL:ENSP00000338860;ENSP00000375594|REFSEQ:NP_060807|H-INV:HIT000028861|VEGA:OTTHUMP00000078377
Tax_Id=9606 Gene_Symbol=ZN
IPI:IPI00647423.2|SWISS-PROT:Q8N819-1|REFSEQ:NP_001073870|VEGA:OTTHUMP00000076687
Tax_Id=9606 Gene_Symbol=FLJ40125 Isoform 1 of
IPI:IPI00219000.2|SWISS-PROT:P27658|TREMBL:Q53XI6|ENSEMBL:ENSP00000261037|REFS
IPI:IPI00291878.4|SWISS-PROT:P35247|ENSEMBL:ENSP00000361366|REFSEQ:NP_003010|H-INV:HIT000039466|VEGA:OTTHUMP00000019944
IPI:IPI00013945.1|SWISS-PROT:P07911-1|TREMBL:Q8NHW8|ENSEMBL:ENSP00000306279|RE
IPI:IPI00000634.1|SWISS-PROT:Q16204|TREMBL:Q6GSG7|ENSEMBL:ENSP00000263102|REFS

I want to plot the pie chart of these gene distribution in the GO
molecular function as a pie chart.  An example is shown in the
following link http://www.proteomesci.com/content/7/1/6/figure/F2?highres=y


Can some one help?

Thanks much in advance.

Merry Christmas!!
