    Cufflinks annotating outputs incorrectly

    Hey,

    I've ran the cufflinks pipeline with both flybase release 5 and UCSC release 3 Drosophila melanogaster annotations, and I'm getting strange annotations in the outputs. The example below is for the UCSC annotation, since it ended up working better with cufflinks overall (but this problem was also the case for the flybase annotation).

    CuffMerge entries for "galectin" gene

    chr2L Cufflinks exon 21821 22941 . + . gene_id "XLOC_000002"; transcript_id "TCONS_00000005"; exon_number "1"; gene_name "galectin"; oId "CUFF.59.1"; nearest_ref "NM_001272859"; class_code "j"; tss_id "TSS2";

    As you can see, in the annotation galectin starts at 71757 on 2L, ending at 76098, however cufflinks has placed it starting at 21821 and ending at 76276.

    Any thoughts on this would be very much appreciated.
    Thanks,

    Gordon
