Hi,

I downloaded the GFF file for S. cerevisiae from NCBI:

ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF_000146045.2_R64/GCF_000146045.2_R64_genomic.gff.gz

I'm trying to open the file with the following command:

txdb <- makeTranscriptDbFromGFF("genomes/Saccharomyces_cerevisiae/GCF_000146045.2_R64_genomic.gff",
                                format="gff3")

 And I get the following error:

You're using an old version of R and the GenomicFeatures package.  Perhaps try upgrading to R-3.2.4 and get the most recent version of GenomicFeatures.  The makeTranscriptDbFromGFF() function has been deprecated, removed, and replaced by makeTxDbFromGFF()

This combination works for me:

txdb <- makeTxDbFromGFF("GCF_000146045.2_R64_genomic.gff", format = "gff3")

Import genomic features from the file as a GRanges object ... OK
Prepare the 'metadata' data frame ... OK
Make the TxDb object ... OK
