Hi!

I am trying to make a TxDB using GenomicFeature R package using my gff3 file but I don't understand the error that the package thought out.

Does anyone know what is happening?

WHAT I AM DOING

library(GenomicFeatures)
gff_path <- '/path/to/gff3'

makeTxDbFromGFF(file = gff_path, format = 'gff3')

WHAT HAPPENS

Import genomic features from the file as a GRanges object ... OK
Prepare the 'metadata' data frame ... OK
Make the TxDb object ... Error in .normarg_makeTxDb_transcripts(transcripts) : 
  values in 'transcripts$tx_strand' must be "+" or "-"
In addition: Warning messages:
1: In makeTxDbFromGRanges(gr, metadata = metadata) :
