Hi,

Following an old vignette on "How to use clusterProfiler to do GO enrichment analysis with unsupported organisms" I've got this error.

library(clusterProfiler)
> Gff2GeneTable("all.gff3", compress=T)
Reading all.gff3: found 813788 rows with classes: character, character, character, integer, integer, character, character, character, character
Error in merge.data.frame(GeneID, geneInfo, by.x = "GeneID", by.y = "GeneID") :
negative length vectors are not allowed

My aim is to use buildGOmap to prepare the annotation files for enrichGO function.

Thanks a lot.

that vignette is pretty old and was remove since BioC 2.14.

Please see also <A: Problem with BuildGOmap() in clusterProfiler>

Thanks a lot. Is there any new function for parsing GFF file?

No. This function is previous design for translating gene ID for bacteria only and not well tested. I think I should remove it from future release.

Thanks again.

Sorry again. Is there any way to use the enrichGO function for unsupported organisms. I also want to use the ontology argument. You said that the go2ont and go2term helper functions may help the separate GO sub_ontology and prepare TERM2NAME data.frame but I couldn't figure out how.
