[BioC] Using annotation package how can I convert the probe > ID's to Gene names.

[Budhayash Gautam]

Hello friends,

i am working on some SMD two color data for Toxoplasma gondii , i have
done differential expression analysis. Now i want to annotate these
genes,

now the problem is that how can i convert the probe ID's to Gene names
using annotation package and with what database because there is no
database in bioconductor related to t. gondii.

if i have to pick these gene names from NCBI then how can i link or
retrieve this information from ncbi collectively as i have to do these
annotation on the level of genome so no. of genes are in thousands...

or if any one can suggest any reading material it will be helpful to
me becoz i am stuck right now how to go ahead.....
