Hi, I came across an error when building the TxDb from GFF as follow:
txdb <- makeTxDbFromGFF(gfffile, format="gff")
Import genomic features from the file as a GRanges object ... OK
Prepare the 'metadata' data frame ... OK
Make the TxDb object ... Error in .get_cds_IDX(type, phase) :
the "phase" metadata column must contain 0, 1, or 2, for all the CDS features
Thanks for your suggestions.
