Can anyone recommend a GTF2.2 validator? There is a link to one on this page but linked page doesn't appear to be working. There is also another validator here but there isn't a readme file so I don't know if it is validating GTF2.2 or earlier version of the file format.
Also on the GTF2.2 page given above it says in the title that GTF2.2 is revised ensembl GTF. Does that mean that ensembl GTF downloads are not valid GTF2.2. If not, is there a means of converting ensembl GTF to GTF2.2. This biostar question here contains a comment which suggests ensembl GTF is GTF2.2
Edit: in response to Brad's comment I want to use GTF2.2 because I am using PLINK/SEQ and the custom annotation databases used by that are imported in GTF2.2 format.
thank you for your time
