When mirpro_gff3_to_gtf is used to transfer NCBI gff file (in gff3) format, we noticed the following problems. (1) For the feature of 'mRNA', 'transcript', 'ncRNA', 'rRNA', 'tRNA', the entry has missed 'transcript_id'.
(2) Also, any feature with the feature of RNAs that is other than 'mRNA' and 'transcript' has been ignored by the program.
Fixed bug.
