filterTranscriptMetadata: Prepare transcript metadata before extending truncated...
In kauralasoo/reviseAnnotations: What the package does (short line)

Retain only genes with >= 2 transcripts and mark CDS start and end 'not found' for incomplete transcripts.

filterTranscriptMetadata(transcript_metadata,
  complete_transcripts = c("protein_coding", "lincRNA"),
  incomplete_transcripts = c("nonsense_mediated_decay",
  "processed_transcript", "retained_intron"))

`transcript_metadata`	Data frame of transcript metadata.
`complete_transcripts`	Biotypes of complete transcripts (CDS start and end NF flags extracted grom GFF)
`incomplete_transcripts`	Biotypes of trnascripts whose start and end are likely to be missing.
