HOMER annotation & GO

[gcorre]

Hi,
I have started using HOMER for peaks detection and annotation from illumina chip-seq data and it actually works well.
But when I try to provide gene expression data using the "-gene" argument or try to obtain GO informations using "-go", no additional information is parsed to the annotation file.
Does someone already experience this issues or do I make something wrong?

HOMER is running on cygwin/window7, added to $path and working well.
typical command line used :

perl annotatePeaks.pl input.bed hg19 -gene expression_data.txt or
perl annotatePeaks.pl input.bed hg19 -go /GO_output

thanks in advance,
