Dear all,

I have a problem when I try to use bioconductor GOSemSim package to calculate the GO semantic similarities between yeast.

geneSim("852494", "854869", ont = "MF", organism="yeast", measure="Resnik")

return below result:

[1] NA
Warning messages:
1: In is.na(go) : is.na() applied to non-(list or vector) of type 'NULL'
2: In is.na(go) : is.na() applied to non-(list or vector) of type 'NULL'

Any comments or advice are welcome.

Thanks
