[BioC] ParseMetaFromGtfFile is.na() error

[Beth Wilmot [guest]]

Hi,
I am using SCAN.UPC and trying to create an annotation file from one concatenated GRCm38.73 fasta file.  I have the matched GRCm38.73.gtf file.  The .gtf file parsing halts near the end of the file and the following error message appears and no output file is generated.  Thanks, Beth

...
Done parsing 1140000 lines from /Mus_musculus.GRCm38.
